<p><a name="introduction" id="introduction"> </a> 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 <i>CMVP</i>
(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.</p>
<h2><a name="connect">How to Connect</a></h2>
<p>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:</p>
<p><a href="http://localhost:27744/">http://localhost:27744/</a></p>
<p>To connect to the administrative web site, use the following
URL:</p>
<p><a href="http://localhost:27777/">http://localhost:27777/</a></p>
<h2><a name="limits">What it does and doesn't do</a></h2>
<p>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. :)</p>
<h2><a name="security">Security</a></h2>
<p>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.<br />
</p>
<h2><a name="configuration">Configuration</a></h2>
<p>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.</p>
<p>INI files for the web servers live in the 'web/' directory off
the CoffeeMud root; by default, all pages to be served go in <i>web/(servername)/</i>,
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.</p>
<p>The configuration options are:</p>
<ul>
<li> <b>PORT</b>=xx : <b>[REQUIRED]</b> <i>(e.g. PORT=80)</i>
<i>(e.g. PORT=80,27744)</i><b><br />
SSLPORT</b>=xx <i>(e.g. SSLPORT=443)</i> <br />
<p>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 <i />pub.ini</i> and <I>admin.ini</I>.</p>
</li>
<li> <b>DEBUGFLAG</b>=xx : <i>(e.g. DEBUGFLAG=false)</i>
<p>An alternative way to turn on debugging messages in the
web server. The more appropriate way is the DEBUG entry in
coffeemud.ini.</p>
</li>
<li> <b>BIND</b>=addr : <i>(e.g. BIND=127.0.0.1)</i>
<p>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.</p>
<p class="bold">The Admin server should be bound to localhost
(or 127.0.0.1) in admin.ini unless you really know what you're doing...</p>
</li>
<li> <b>DEFAULTPAGE</b>=filename : <b>[REQUIRED]</b> <i>(e.g.
DEFAULTFILE=index.cmvp)</i>
<p>Sets the default filename to be appended if none is
specified in the request. This is in common.ini.</p>
</li>
<li> <b>SSLKEYSTOREPATH=</b>path/to/keystore.jks <span
style="font-style: italic;">(e.g. SSLKEYSTOREPATH=keys/keystore.jks)</span><b><br />
SSLKEYSTOREPASSWORD=</b>keystore file password <span
style="font-style: italic;">(e.g. SSLKEYSTOREPASSWORD=mypassphrase)</span><b><br />
SSLKEYSTORETYPE=</b>JKS <span style="font-style: italic;">(are there
other useful values for this?)</span><b><br />
SSLKEYMANAGERENCODING=</b>SunX509 <span style="font-style: italic;">(are
there other useful values for this?)</span><b><br />
<span style="font-style: italic;" /></b>
<p>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</p>
</li>
<li> <span style="font-weight: bold;">FILECACHEEXPIREMS=</span>milliseconds
<span style="font-style: italic;">(e.g.
FILECACHEEXPIREMS=300000)</span><span style="font-weight: bold;"><br />
FILECACHEMAXBYTES=</span>#bytes <span style="font-style: italic;">(e.g.
FILECACHEMAXBYTES=65535)</span><span style="font-weight: bold;"><br />
FILECACHEMAXFILEBYTES=</span>#bytes <span style="font-style: italic;">(e.g.
FILECACHEMAXFILEBYTES=8192)</span><span style="font-weight: bold;"><br />
FILECOMPMAXBYTES=</span><span style="font-weight: bold;">#bytes <span
style="font-style: italic;">(e.g. FILECOMPMAXBYTES=16485760)</span>
<p>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.</p>
</span></li>
<li><span style="font-weight: bold;">REQUESTMAXBODYBYTES</span>=#bytes
<span style="font-style: italic;">(e.g.
REQUESTMAXBODYBYTES=2097152)</span><br />
<span style="font-weight: bold;">REQUESTMAXIDLEMS</span>=milliseconds
<span style="font-style: italic;">(e.g.
REQUESTMAXIDLEMS=30000)</span><br />
<span style="font-weight: bold;">REQUESTLINEBUFBYTES</span>=#bytes
<span style="font-style: italic;">(e.g.
REQUESTLINEBUFBYTES=65535)</span><br />
<span style="font-weight: bold;">REQUESTMAXALIVESECS</span>=seconds
<span style="font-style: italic;">(e.g.
REQUESTMAXALIVESECS=15)</span><br />
<span style="font-weight: bold;">REQUESTMAXPERCONN</span>=#requests
<span style="font-style: italic;">(e.g. REQUESTMAXPERCONN=20)</span><br />
<br />
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). <br />
<br />
All of these are normally defined in common.ini, except for
REQUESTMAXALIVESECS, which is defined in pub.ini and admin.ini by
default.<br />
</li>
<li><span style="font-weight: bold;">CORETHREADPOOLSIZE</span>=#threads
<span style="font-style: italic;">(e.g. CORETHREADPOOLSIZE=1)</span><br />
<span style="font-weight: bold;">MAXTHREADS</span>=#threads <span
style="font-style: italic;">(e.g. MAXTHREADS=10)</span><br />
<span style="font-weight: bold;">MAXTHREADIDLEMILLIS</span>=milliseconds
<span style="font-style: italic;">(e.g.
MAXTHREADIDLEMILLIS=60000)</span><br />
<span style="font-weight: bold;">MAXTHREADQUEUESIZE</span>=#tasks
<span style="font-style: italic;">(e.g.
MAXTHREADQUEUESIZE=500)</span><br />
<span style="font-weight: bold;">MAXTHREADTIMEOUTSECS</span>=seconds
<span style="font-style: italic;">(e.g.
MAXTHREADTIMEOUTSECS=30)</span><br />
<br />
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<br />
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<br />
work on any one task (MAXTHREADTIMEOUTSECS).<br />
<br />
All of these are normally defined in common.ini, except
for MAXTHREADTIMEOUTSECS, which is defined in pub.ini and
admin.ini by
default.<br />
</li>
<li> <b>ADMIN</b>=true/false
<p>This allows admin macros to run on this server or not (see
below). This is always in admin.ini, for obvious reasons.</p>
</li>
<li> <span style="font-weight: bold;">ERRORPAGE</span>=path/filename
<span style="font-style: italic;">(e.g.
ERRORPAGE=/web/pub.templates/errorpage.mwhtml)</span>
<p>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.</p>
</li>
</ul>
<h2><a name="virtualdir">Virtual Directories</a></h2>
<p>To permit web access to the files in particular CoffeeMud
directories, you can specify <b>MOUNT/virtualdir=physicaldir</b> in
the pub.ini or admin.ini files; for example, <b>MOUNT/guides=guides</b>
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 <span
style="font-weight: bold;">MOUNT/mydomain.com:8080/files=/web/pub</span>
would allow browser urls such as http://www.mydomain.com:8080/files to
access the /web/pub folder.</p>
<h2><a name="virtualpages">CoffeeMud Virtual Pages</a></h2>
<p>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).</p>
<p>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:</p>
<p>@MacroName?PARAMETER&PARM2=VALUE&PARM3@</p>
<p>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):</p>
<p>@MacroOne?@@MacroTwo?PARM@@&@@MacroThree?PARM@@ @</p>
<p>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:</p>
<p>@MacroOne?@@MacroTwo?@@@MacroThree?PARM@@@ @@ @</p>
<p>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.</p>

<h2><a name="customize">Customizing the error page</a></h2>
<p>Simply create a file <i>errorpage.mwhtml</i> 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.</p>
<h2><a name="add">Adding new macros to CMVP</a></h2>
<p>Create the new .java file in the <i>com/planet_ink/coffee_mud/WebMacros</i>
directory; all classes in this directory are loaded as macros by
default. The new class should inherit from <code>StdWebMacro</code> in
the <code>com.planet_ink.coffee_mud.WebMacros</code> package.</p>
<p>The package of the new class should implement the interface <code>com.planet_ink.coffee_mud.WebMacros.interfaces.WebMacro.</code></p>
<p>The <code>name()</code> 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.</p>
<p>Finally, the <code>runMacro()</code> function returns the
String data you wish to insert into the processed output; it takes as
parameters a reference to the <i>HTPRequest</i> that is calling the
macro, and a String representing the data after the first question
mark? in the macro reference.</p>
<p>If <code>runMacro()</code> returns <i>null</i>, the string
[Error] is used to replace the macro.
<b>If <code>runMacro()</code> returns <i>@break@</i>, this will cause a @loop@-@back@ segment
to terminate</b>.</p>
<p>Example: this is the complete code for the <b>@HTTPCLIENTIP@</b>
macro (HTTPclientIP.java):</p>

<h2><a name="javascript">Using Javascript in your pages</a></h2>
<p>The CoffeeMud web server allows you to use the Javascript
language to generate the tags and data which make up your <strong>cmvp</strong>
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 <a href="Programming.html">Programmers Guide</a>. The web server
makes the <code>HTTPRequest request()</code> object available to the
script, as well as the method <code>void write(String s)</code> for
writing text into the page.</p>
<p>Here is our first example:</p>
<pre><HTML><br /><BODY><br />@jscript@<br />var x=request().getClientAddress().getHostAddress();<br />write('<P>Your IP Address is <B>'+x+'</B>.</P>');<br />@/jscript@<br /></BODY><br /></HTML><br /></pre>
<p>Notice how we used the <code>write()</code> method to insert
our HTML into the page. We also used the <code>request()</code> object
to fetch the client ip address. Now here is a more involved example:</p>
<pre><HTML><br /><HEAD><br /><TITLE>My JavaScript Enabled Web Page</TITLE><br /></HEAD><br /><BODY><br /><H1>An Example of using JavaScript in a CMVP Web Page to fetch MUD Server data.</H1><br /><br />@jscript@<br />var lib=Packages.com.planet_ink.coffee_mud.core.CMLib;<br />// define a shortcut to the CoffeeMud libraries.<br /><br />var randomRoom=lib.map().getRandomRoom();<br />var randomArea=lib.map().getRandomArea();<br />// finding random rooms and areas is easy<br /><br />var randomMob=null;<br />var randomItem=null;<br />// assign our random mobs and items to null until they are found<br /><br />var attempts=1000;<br />// finding random items and mobs is more difficult. We will<br />// select a random room, and attempt to pick out a random mob<br />// and/or item from the room. We will do this a maximum of 1000<br />// times before giving up, until we find one of each.<br />while(((--attempts)>0)&&((randomMob==null)||(randomItem==null)))<br />{<br /> var room=lib.map().getRandomRoom();<br /> if((randomMob==null)&&(room.numInhabitants()>0))<br /> {<br /> randomMob=room.fetchRandomInhabitant();<br /> }<br /> if((randomItem==null)&&(room.numItems()>0))<br /> {<br /> randomItem = room.getRandomItem();<br /> }<br />} //now we have all our random things. We could easily insert our HTML using<br /> // the write() method as we did in example 1. To be fancy, however, we'll use the<br /> // the request() object to assign the names of our selections to HTTP Request<br /> // strings.<br /><br />request().addFakeUrlParameter("RANDOMROOM",randomRoom.displayText());<br />request().addFakeUrlParameter("RANDOMAREA",randomArea.name());<br />if(randomMob!=null)<br /> request().addFakeUrlParameter("RANDOMMOB",randomMob.name());<br />if(randomItem!=null)<br /> request().addFakeUrlParameter("RANDOMITEM",randomItem.name());<br />// now we exit back and continue with our HTML, using standard CMVP web macros<br />// to fetch the random names we saved.<br />@/jscript@<br /><br /><FONT FACE="Courier New"><br /><B>A random area: <B>@RequestParameter?RANDOMAREA@<BR><br /><B>A random room: <B>@RequestParameter?RANDOMROOM@<BR><br /><B>A random mob : <B>@RequestParameter?RANDOMMOB@<BR><br /><B>A random item: <B>@RequestParameter?RANDOMITEM@<BR><br /><br /></FONT><br /><P><br /></BODY><br /></HTML><br /></pre>
