<P>
|
|
Each Apache module is described using a common format that looks
|
|
like this:

This indicates how tightly bound into the Apache Web server the
|
|
module is; in other words, you may need to recompile the server in
|
|
order to gain access to the module and its functionality. Possible
|
|
values for this attribute are:
|
|
</P>
|
|
<DL>
|
|
<DT><STRONG>MPM</STRONG>
|
|
</DT>
|
|
<DD>A module with status "MPM" is a <a
|
|
href="../mpm.html">Multi-Processing Module</a>. Unlike the other
|
|
types of modules, Apache must have one and only one MPM in use at
|
|
any time. This type of module is responsible for basic request
|
|
handling and dispatching.
|
|
<P>
|
|
</P>
|
|
<DT><STRONG>Base</STRONG>
|
|
</DT>
|
|
<DD>A module labeled as having "Base" status is compiled
|
|
and loaded into the server by default, and is therefore normally
|
|
available unless you have taken steps to remove the module from your
|
|
configuration.
|
|
<P>
|
|
</P>
|
|
</DD>
|
|
<DT><STRONG>Extension</STRONG>
|
|
</DT>
|
|
<DD>A module with "Extension" status is not normally
|
|
compiled and loaded into the server. To enable the module and its
|
|
functionality, you may need to change the server build
|
|
configuration files and re-compile Apache.
|
|
<P>
|
|
</P>
|
|
</DD>
|
|
<DT><STRONG>Experimental</STRONG>
|
|
</DT>
|
|
<DD>"Experimental" status indicates that the module is
|
|
available as part of the Apache kit, but you are on your own if you
|
|
try to use it. The module is being documented for completeness,
|
|
and is not necessarily supported.
|
|
<P>
|
|
</P>
|
|
</DD>
|
|
<DT><STRONG>External</STRONG>
|
|
</DT>
|
|
<DD>Modules which are not included with the base Apache
|
|
distribution ("third-party modules") may use the
|
|
"External" status. We are not responsible for, nor do we
|
|
support such modules.
|
|
<P>
|
|
</P>
|
|
</DD>
|
|
</DL>
|
|
|
|
<HR>
|
|
<H2><A NAME="SourceFile">Source File</A></H2>
|
|
<P>
|
|
This quite simply lists the name of the source file which contains
|
|
the code for the module. This is also the name used by the <A
|
|
HREF="core.html#ifmodule"><CODE><IfModule></CODE></A>
|
|
directive.
|
|
</P>
|
|
|
|
<HR>
|
|
<H2><A NAME="ModuleIdentifier">Module Identifier</A></H2>
|
|
<P>
|
|
This is a string which identifies the module for use in the <A
|
|
HREF="mod_so.html#loadmodule">LoadModule</A> directive when
|
|
dynamically loading modules. In particular, it is the name
|
|
of the external variable of type module in the source file.
|
|
</P>
|
|
|
|
<HR>
|
|
<H2><A NAME="Compatibility">Compatibility</A></H2>
|
|
<P>
|
|
If the module was not part of the original Apache version 2
|
|
distribution, the version in which it was introduced should be listed
|
|
here.
