# CoffeeMud Web Server
Introduction How to Connect What it does and doesn't do Security Configuration Virtual Directories CoffeeMud Virtual Pages Customizing the error pages Adding new macros to CMVP Using Javascript in your pages Siplet and SipletInterface | The CoffeeMud Web Server is a simple, extensible web server that runs as part of CoffeeMud; it uses HTTP 1.1 to communicate with a web browser. In addition to being able to serve standard HTML web pages, it also supports a simple server-processed form of HTML called CMVP (Coffee MUD Virtual Pages) - this allows the server to insert information into the page before sending it to the browser. This document assumes you have some familiarty with HTTP, mime types, and stuff like that. ## How to Connect By default, the public (pub) web site listens on ports 80 and 27744 and the administrative (admin) web site on port 27777. To browse the default public web site, just open up the following URL in your browser: http://localhost:27744/ To connect to the administrative web site, use the following URL: http://localhost:27777/ ## What it does and doesn't do It supports GET, urlencoded and multipart POST requests, and HEAD requests. It supports custom servlets, cookies, sessions, SSL, gzip and deflate encodings, pipelining, etag support, ranged requests, async IO (fast!), mapping mime types to java converter and filter classes, file caching, and more. It supports numerous coded web macros, as well as inline server-side Javascripts to create custom pages. It does not make coffee, but it does make CoffeeMud better. :) ## Security The web server uses explicitly mounted directories to control access to your CoffeeMud filesystem (CMFS). You can mount more directories or remove existing ones by changing the MOUNT list in the configuration files (see below). The default installation runs one of the two web servers with an "ADMIN=true" flag in its configuration, allowing it to access the more powerful CoffeeMud macros. The web server also supports SSL (https). However, this is not turned on by default, since it requires access to a special (and pricey!) SSL web certificate from a respected certification agency, such as Verisign. To learn more about setting this up, see the SSLPORT entry and the information under SSL CONFIGURATION in the common.ini configuration file. Lastly, the configuration files have a BIND entry that can be used to restrict connections to your administration server, but is not set by default. ## Configuration The default installation of CoffeeMud has two inbuilt web servers, named 'pub' and 'admin'. The web servers are enabled with the line 'RUNWEBSERVERS=pub,admin' in 'coffeemud.ini'; absence of this line will cause the web servers not to be loaded. INI files for the web servers live in the 'web/' directory off the CoffeeMud root; by default, all pages to be served go in web/(servername)/, though this can be overridden. Options are placed in either 'web/common.ini' or 'web/(servername).ini'; an option in the latter will override one in common. This means that some configuration options are in web/pub.ini for the "pub" server, web/admin.ini for the "admin" server, and web/common.ini for Both. The configuration options are: PORT=xx : [REQUIRED] (e.g. PORT=80) (e.g. PORT=80,27744) SSLPORT=xx (e.g. SSLPORT=443) Sets the port number the web server will listen for HTTP and HTTPS requests on; this cannot be the same port as the main MUD server or another web servers. This list may be comma delimited to start more than one instance on different ports. Normally this would go in pub.ini and admin.ini. DEBUGFLAG=xx : (e.g. DEBUGFLAG=false) An alternative way to turn on debugging messages in the web server. The more appropriate way is the DEBUG entry in coffeemud.ini. BIND=addr : (e.g. BIND=127.0.0.1) Causes the server to be bound to a specific address; this is useful on multi-homed machines or if you wish to prevent public access to the pages. Identical to MUD server usage. The Admin server should be bound to localhost (or 127.0.0.1) in admin.ini unless you really know what you're doing... DEFAULTPAGE=filename : [REQUIRED] (e.g. DEFAULTFILE=index.cmvp) Sets the default filename to be appended if none is specified in the request. This is in common.ini. SSLKEYSTOREPATH=path/to/keystore.jks (e.g. SSLKEYSTOREPATH=keys/keystore.jks) SSLKEYSTOREPASSWORD=keystore file password (e.g. SSLKEYSTOREPASSWORD=mypassphrase) SSLKEYSTORETYPE=JKS (are there other useful values for this?) SSLKEYMANAGERENCODING=SunX509 (are there other useful values for this?) Allows you to turn on support for SSLv3 via a java keystore file (SSLKEYSTOREPATH), but you can specify any key file format that java supports, so long as you also specify its type (SSLKEYSTORETYPE). If the keystore/file has a password, specify it also (SSLKEYSTOREPASSWORD). If any of this stuff is invalid, the web server will not attempt to listen on your SSL ports. These are normally in common.ini FILECACHEEXPIREMS=milliseconds (e.g. FILECACHEEXPIREMS=300000) FILECACHEMAXBYTES=#bytes (e.g. FILECACHEMAXBYTES=65535) FILECACHEMAXFILEBYTES=#bytes (e.g. FILECACHEMAXFILEBYTES=8192) FILECOMPMAXBYTES=#bytes (e.g. FILECOMPMAXBYTES=16485760) The data for your web site can be cached in memory for better performance. To tune this feature, you can specify the amount of time a cache entry lives in memory (FILECACHEEXPIREMS), how much TOTAL file data will be stored in the cache before it starts forcing entries out of the cache to make more room (FILECACHEMAXBYTES), and the maximum size of any one file stored in the cache (FILECACHEMAXFILEBYTES). The maximum size of any file that can be compressed is FILECOMPMAXBYTES. To turn any of these off entirely, specify a value of 0. If you have lots of allocated java memory, however, making those numbers larger will help performance. These are also in common.ini. REQUESTMAXBODYBYTES=#bytes (e.g. REQUESTMAXBODYBYTES=2097152) REQUESTMAXIDLEMS=milliseconds (e.g. REQUESTMAXIDLEMS=30000) REQUESTLINEBUFBYTES=#bytes (e.g. REQUESTLINEBUFBYTES=65535) REQUESTMAXALIVESECS=seconds (e.g. REQUESTMAXALIVESECS=15) REQUESTMAXPERCONN=#requests (e.g. REQUESTMAXPERCONN=20) This is some fine tuning regarding constraints on http requests. You can specify the maximum size of any request body (REQUESTMAXBODYBYTES), the number of milliseconds a connection can sit idle between requests (REQUESTMAXIDLEMS), The maximum size of any one line of request data, such individual headers, url length, etc (REQUESTLINEBUFBYTES), the longest amount of time a connection can hang around sending requests to the web server and receiving data (REQUESTMAXALIVESECS), and the maximum number of requests that can be made on a single connection (REQUESTMAXPERCONN). All of these are normally defined in common.ini, except for REQUESTMAXALIVESECS, which is defined in pub.ini and admin.ini by default. CORETHREADPOOLSIZE=#threads (e.g. CORETHREADPOOLSIZE=1) MAXTHREADS=#threads (e.g. MAXTHREADS=10) MAXTHREADIDLEMILLIS=milliseconds (e.g. MAXTHREADIDLEMILLIS=60000) MAXTHREADQUEUESIZE=#tasks (e.g. MAXTHREADQUEUESIZE=500) MAXTHREADTIMEOUTSECS=seconds (e.g. MAXTHREADTIMEOUTSECS=30) Now for the really geeky stuff. The web server will try to process as many requests at the same time as it can by spawning threads when it needs to. You can tweek this process right here. You can specify the minimum number of threads to keep hanging around waiting to process requests (CORETHREADPOOLSIZE), as well as the absolute maximum number (MAXTHREADS). You can also specify the amount of time a thread goes unused before it is shut down (MAXTHREADIDLEMILLIS), the maximum number of tasks that can be queued up waiting for thread time (MAXTHREADQUEUESIZE), and the absolute maximum amount of time a thread is allowed to work on any one task (MAXTHREADTIMEOUTSECS). All of these are normally defined in common.ini, except for MAXTHREADTIMEOUTSECS, which is defined in pub.ini and admin.ini by default. ADMIN=true/false This allows admin macros to run on this server or not (see below). This is always in admin.ini, for obvious reasons. ERRORPAGE=path/filename (e.g. ERRORPAGE=/web/pub.templates/errorpage.mwhtml) When an error or exception is generated, which page is displayed. This is a LOCAL PATH, either relative or absolute. This is normally defined in the pub.ini and admin.ini files. ## Virtual Directories To permit web access to the files in particular CoffeeMud directories, you can specify MOUNT/virtualdir=physicaldir in the pub.ini or admin.ini files; for example, MOUNT/guides=guides creates a virtual directory with access to the player guides. If you want, you can also tie particular web hostnames and ports to particular directories. For example MOUNT/mydomain.com:8080/files=/web/pub would allow browser urls such as http://www.mydomain.com:8080/files to access the /web/pub folder. ## CoffeeMud Virtual Pages Kind of misnamed (these pages in their original, very different incarnation didn't exist at all), this is typically a HTML or plaintext file that is preprocessed by the server before being dispatched to the browser. Preprocessing is a simple search-and-replace; NO ACCOUNT is taken of where the macro appears within the file (ie, macros within comments or quoted strings will be replaced). Macros are always surrounded by the AT sign (@), and are thus delineated in the page. Any parameters required for a macro always follow the macro name and a Question Mark (?). Further parameters are separated by the Ampersand (&) character. Each parameter may optionally be an equation, where the name is on the left of an equal sign, and its value on the right. An example of all this in action would be: @MacroName?PARAMETER&PARM2=VALUE&PARM3@ Macros may be embedded in each other ONLY if the embedded macros are part of the parameters of the host macro, which means they must follow the Question Mark. Also, for each level of embedding, an extra At sign (@) character is used around the macro. To avoid confusion, the closing At signs (@) should be separated by spaces. Here is an example of embedded Macros (in this case, two macros are used for each of two parameters to a first macro (MacroOne): @MacroOne?@@MacroTwo?PARM@@&@@MacroThree?PARM@@ @ Notice the space before the final At sign (@). Now, here is an example of double-embedding, where MacroThree is embedded as the parameter to MacroTwo, which is embedded as the parameter to MacroOne: @MacroOne?@@MacroTwo?@@@MacroThree?PARM@@@ @@ @ Here are the macros defined so far. Keep in mind the difference between a Macro parameter (things which follow the first Question mark in a macro), and a Request Parameter (data submitted from a <FORM> on a web page, or on the URL line of a GET request). Macro parms will be abbreviated to MacParm, while Request Parameters will be abbreviated to ReqParm.

AddRandomFile | The parameters for this macro are a list of file names. This macro inserts the contents of one of the files at random into the current document. If the parameter LINKONLY is included, this macro will instead insert the path and file name of the random file.
AddRandomFileFromDir | The parameters for this macro are a list of directory names. This macro inserts the contents of one of the files at random from one of the directories into the current document. If the parameter LINKONLY is included, this macro will instead insert the path and file name of the random file.

Each <TD> element has style-sheet class cmAreaTblEntry. The area list may only be obtained while the mud server is running; otherwise a simple table containing a game-not-running message is returned.
Authenticate | Requires ReqParms LOGIN and PASSWORD to be unencrypted login data, or AUTH to be encrypted login data. If MacParm AUTH specified, will return the encrypted login data. Otherwise, returns "true" if login is valid, and "false" otherwise.
back | Denotes the looping point for a @loop@ block. See the @loop@ macro.
BanListMgr | Handles the banned user list. MacParm RESET will clear ReqParm BANNEDONE. MacParm NEXT will set BANNEDONE to the next banned user or ip. MacParm NEXT returns @break@ when the list has been completed, or "" if MacParm "EMPTYOK" also found. MacParm DELETE will delete banneded name/ip that ReqParm BANNEDONE is se to.

break | Stops inserting text into a web page at the current point, skips ahead to the next @back@ macro found, and starts again. If no @back@ macro is found, the page will not continue to be evaluated. See the @loop@ macro. This macro is actually returned by many other macros as a means of creating breaks in loops.
ChannelBackLogNext | Requires ReqParms LOGIN and PASSWORD to be unencrypted login data, or AUTH to be encrypted login data. Also requires CHANNEL to be the name of a valid channel. Returns the next available channel message, and sets ReqParm CHANNELBACKLOGNUM. Will not break out if MacParm EMPTYOK is given.

ChkReqParmBreak | Evaulates to the string " @break@" (see the break macro) if the specified Request parameters are equal to the values given. It returns "" otherwise. For example, @ChkReqParmBreak?PARM=VALUE@ would return " @break@" if PARM is equal to VALUE, and "" otherwise. See the @loop@ macro for more information on how this might be useful.
ClanData | Requires ReqParm CLAN be set to a valid clan id. Returns information about that clan depending on MacParms found. Valid MacParms include: PREMISE, RECALL, DONATION, TAX, EXP, CCLASS, AUTOPOSITION, STATUS, ACCEPTANCE, TYPE, POINTS, CLANIDRELATIONS (also requires ReqParm CLANID), MEMBERSTART (sets ReqParm CLANMEMBER; like ClanNext?RESET, but for clan members list), MEMBERNEXT (goes with MEMBERSTART), MEMBERNAME, MEMBERPOS (these last two require MEMBERSTART/MEMBERNEXT use)

ExitData | MUDGrinder support macro for showing exit data on maps. Too complicated to describe.
for | The parameters for this macro are a variable name followed by an equal sign (=) followed by another macro name which evaluates to the a comma-delimited string. That macro does not follow the embedding rules above. This macro requires an @next@ macro, and will assign a request parameter of the same name as the variable name equal to an entry in the string returned by the macro in each iteration. For example: @for?EXITFLAG=ExitData?ISGENERIC&NAME@ would iterate twice, with reqparm EXITFLAG = true (or false) the first time, and a NAME the second time. @for?COUNTER=1,2,3,4@ would iterate 4 times, with reqparm COUNTER = 1 on the first iteration, then 2, 3 and finally 4.
HelpTopics | Handles the showing of help topics. MacParm RESET will clear ReqParm HELPTOPIC and HELPFIRSTLETTER. MacParm NEXT will set HELPTOPIC to the next help topic depending on other MacParms found (SHORT to not include abilities, ARCHON to show only Archon Help, BOTH to show Archon and Player Help, FIRSTLETTER=val to show only those with starting letter (ReqParm HELPFIRSTLETTER does the same). MacParm NEXT returns @break@ when the list has been completed, or "" if MacParm "EMPTYOK" also found. MacParm NEXTLETTER sets ReqParm HELPFIRSTLETTER to next letter in the alphabet, returning @break@ when done. MacParm DATA returns the help text denoted by ReqParm HELPTOPIC.
HTTPclientIP | Returns the client's IP address.
HTTPstatus | Returns the http return code; this is normally of no use ("200 OK") unless customising the error page.
HTTPstatusInfo | Returns additional http status information; this is normally of no use unless customising the error page.
if | The Single, Required parameter for this macro is another macro name which evaluates to the words "true" or something else (which is defined as false). That macro does not follow the embedding rules above. This macro requires an @endif@ macro, and may optionally have an @else@ macro. The "!" character may follow the "?" to negate the value of the expression. For example: @if?CheckReqParm?PARM=VALUE@ @if?!CheckReqParm?PARM=VALUE@ would return true and false (or vis-versa) depending whether the request parameter PARM was equal to VALUE.
ItemData | MUDGrinder macro for support of mob and room items. Too complicated to describe.
JournalFunction | Requires ReqParm JOURNAL be set to a valid journal name, and an authenticatable user found (see Authenticate). If MacParm NEWPOST found, along with ReqParms TO, SUBJECT, and NEWTEXT, a new post is added. If ReqParm JOURNALMESSAGE is set to a valid message number for this journal, then MacParm DELETE will delete the message. If MacParm REPLY and ReqParm NEWTEXT found, a reply added to the designated message.
JournalInfo | Requires ReqParm JOURNAL be set to a valid journal name. Returns information about the journal depending on MacParms found. Valid MacParms include: COUNT, to return messages found. If ReqParm JOURNALMESSAGE is set to a valid message number for this journal, and an authenticatable user is found (see Authenticate) additional MacParms may be used to get information about that message. These MacParms include: KEY, FROM, DATE, TO, SUBJECT, MESSAGE
JournalMessageNext | Requires ReqParm JOURNAL be set to a valid journal name, and an authenticatable user found (see Authenticate). Sets the ReqParm JOURNALMESSAGE to the next message found in the given journal. Returns @break@ when the list has been completed, or "" if MacParm "EMPTYOK" found. Accepts MacParm of RESET to restart listing.

LogViewer | Returns the CoffeeMud log file.
loop | Repeatedly inserts into the page the contents between this macro and the corresponding @back@ until a @break@ macro located inside the block is processed. This @break@ string is most often returned by a macro processed within the block, but may also be embedded in an @if?@ macro block as well.
MobData | MUDGrinder macro for viewing room mob data. Too complicated to describe.
MUDGrinder | The main processing macro for the MUDGrinder area-editing tool. This macro runs as an admin macro. See the MUDGrinder guide for more information. There are too many parameters and options here to mention.

WebServerName | Returns just the name of the web server.
WebServerPort | Returns the port number the web server is running on.
WebServerVersion | Returns the name and version of the web server.
## Customizing the error page Simply create a file errorpage.mwhtml in the template directory of the server; at some point on the page you should use the @HTTPSTATUS@ and @HTTPSTATUSINFO@ macros. Note that the template directory is served as though it were in the specified path - images and stylesheets should therefore go in the server's base directory. ## Adding new macros to CMVP Create the new .java file in the com/planet_ink/coffee_mud/WebMacros directory; all classes in this directory are loaded as macros by default. The new class should inherit from `StdWebMacro` in the `com.planet_ink.coffee_mud.WebMacros` package. The package of the new class should implement the interface `com.planet_ink.coffee_mud.WebMacros.interfaces.WebMacro.` The `name()` member should return the name of your new macro (it will be capitalized and the @ symbols added by StdWebMacro) - the name doesn't have to match the class name but it is recommended to avoid confusion. Finally, the `runMacro()` function returns the String data you wish to insert into the processed output; it takes as parameters a reference to the HTPRequest that is calling the macro, and a String representing the data after the first question mark? in the macro reference. If `runMacro()` returns null, the string [Error] is used to replace the macro. If `runMacro()` returns @break@, this will cause a @loop@-@back@ segment to terminate. Example: this is the complete code for the @HTTPCLIENTIP@ macro (HTTPclientIP.java):
    package com.planet_ink.coffee_mud.WebMacros;

    import com.planet_ink.coffee_web.interfaces.*;

    public class HTTPclientIP extends StdWebMacro

    	public String name()	{return "HTTPclientIP";}

    	public String runMacro(HTTPRequest httpReq, String parm)
    	{

If your macro is intended to be for the admin server only, you can override the `.isAdminMacro()` member to return `true.` ## Using Javascript in your pages The CoffeeMud web server allows you to use the Javascript language to generate the tags and data which make up your cmvp web pages. The Javascript to do this is inserted directly into your web page at the point where you want the script-generated content to appear using the embedded macros@jscript@ and @/jscript@. The script included between those two tags will follow the rules for JavaScripting found in the Programmers Guide. The web server makes the `HTTPRequest request()` object available to the script, as well as the method `void write(String s)` for writing text into the page. Here is our first example:
    <HTML>
    <BODY>
    @jscript@
    var x=request().getClientAddress().getHostAddress();
    write('<P>Your IP Address is <B>'+x+'</B>.</P>');
    @/jscript@
    </BODY>
    </HTML>
Notice how we used the `write()` method to insert our HTML into the page. We also used the `request()` object to fetch the client ip address. Now here is a more involved example:
    <HTML>
    <HEAD>
    <TITLE>My JavaScript Enabled Web Page</TITLE>
    </HEAD>
    <BODY>
    <H1>An Example of using JavaScript in a CMVP Web Page to fetch MUD Server data.</H1>

    @jscript@
    var lib=Packages.com.planet_ink.coffee_mud.core.CMLib;
    // define a shortcut to the CoffeeMud libraries.

    var randomRoom=lib.map().getRandomRoom();
    var randomArea=lib.map().getRandomArea();
    // finding random rooms and areas is easy

    var randomMob=null;
    var randomItem=null;
    // assign our random mobs and items to null until they are found

    var attempts=1000;
    // finding random items and mobs is more difficult.  We will
    // select a random room, and attempt to pick out a random mob
    // and/or item from the room.  We will do this a maximum of 1000
    // times before giving up, until we find one of each.
    while(((--attempts)>0)&&((randomMob==null)||(randomItem==null)))
    {
      var room=lib.map().getRandomRoom();
      if((randomMob==null)&&(room.numInhabitants()>0))
      {
        randomMob=room.fetchRandomInhabitant();
      }
      if((randomItem==null)&&(room.numItems()>0))
      {
        randomItem = room.getRandomItem();
      }
    } //now we have all our random things. We could easily insert our HTML using
      // the write() method as we did in example 1.  To be fancy, however, we'll use the
      // the request() object to assign the names of our selections to HTTP Request
      // strings.

    request().addFakeUrlParameter("RANDOMROOM",randomRoom.displayText());
    request().addFakeUrlParameter("RANDOMAREA",randomArea.name());
    if(randomMob!=null)
     request().addFakeUrlParameter("RANDOMMOB",randomMob.name());
    if(randomItem!=null)
     request().addFakeUrlParameter("RANDOMITEM",randomItem.name());
    // now we exit back and continue with our HTML, using standard CMVP web macros
    // to fetch the random names we saved.

## Siplet and SipletInterface The CoffeeMud web server supports HTTP Web Sockets technology, and uses it to provide a web game client. This client can be found on your public pages with the Play Now link, which is directed at /web/siplet/index.html. The client supports ANSI color, Telnet codes, MSP, and MXP protocols. Input is entered through the large text box at the bottom, and the numbered tabs along the top can be used to open or navigate through multiple sessions. GMCP command can be sent to the mud through Siplet by entering the command into the input box prefixed with \GMCP and a space. MSDP commands can also be sent to the mud with the \MSDP prefix. Siplet communicates with the mud through WebSockets by using a special URL-triggered WebMacro called SipletInterface, which is then used to send commands. The Url to connect to SipletInterface is ws://localhost:27744/SipletInterface where 'localhost' is your coffeemud web server domain name, and '27744' is the port of your public pages. SipletInterface supports the following commands from the browser: Connect Command: CONNECT&URL=<mud telnet host>&PORT=<mud port> This command establishes a connection through the SipletInterface to the target mud, which is hopefully yours. The host and port should be the same ones used in any normal web client, and should be url-encoded if there are any special characters that might interfere with the format of the command. After sending this command, the next data received on the web socket will be the formatted response to this command. The response is in the following format: <success true/false>;<token>;<siplet info string><token>; The success argument is the string 'true' or 'false', depending on whether the connection was successful. The token argument is a delimiter token string that must be preserved throughout the web socket session. The siplet info string is some information about the SipletInterface, such as 'Siplet V2.3.0 (C)2005-20XX Bo Zimmerman' The final token and semicolon are the same as above, and denote the end of the siplet info string, and the end of this response. An example response for a successful connection might be: true;318cae09;Siplet V2.2.0 (C)2005-2017 Bo Zimmerman318cae09; Disconnect Command: DISCONNECT&TOKEN=<connection token> This command tells the socket that the connection to the mud should be closed. The connection can then be re-used for a new connection. The token argument is the same delimiter token string that was received from the Connect command above. After sending this command, the next data received on the web socket will be the formatted response to this command. The response is in the following format: <success true/false>; The success argument is the string 'true' or 'false', depending on whether the disconnection was successful. Poll Command: POLL&TOKEN=<connection token> This command acts like a ping command to the siplet interface, and is used to let the interface know that the web client is still there, and to check whether the connection to the underlying mud is still active. The token argument is the same delimiter token string that was received from the Connect command above. This command should be sent every 20 seconds or so to prevent the SipletInterface from timing out your connection. After sending this command, the next data received on the web socket will be the formatted response to this command. The response is in the following format: <success true/false>;<html><token>;<javascript><token>; The success argument is the string 'true' or 'false', depending on whether the connection to the underlying mud is still active. If false is returned, your connection is lost.. The html string is a block of html that should be added to the browser window. The token argument is the same delimiter token string that was received from the Connect command above.. The javascript string is a block of javascript that can be executed with the eval() command, or ignored. An example response for a successful connection might be: true;You have connected to the mud!318cae09;window.alert('hi')318cae09; Send Data Command: SENDATA&TOKEN=<connection token>&DATA=<string to send> This command is used to send user input and commands to the mud through the web socket. The token argument is the same delimiter token string that was received from the Connect command above, and the <string to send> is the user input. After sending this command, the next data received on the web socket will be the formatted response to this command, which is identical to the Poll Command output above. * Note: After connection to a mud through the web socket, you will periodically receive spontaneous packets that are not in response to any particular command. These are incoming data from the mud, and will be formatted exactly the same as if you had sent a Poll Command above.
