16 <H1 ALIGN="CENTER">Terms Used to Describe Apache Modules</H1>
19 Each Apache module is described using a common format that looks
26 ><STRONG>Status:</STRONG></A> <EM>status</EM>
31 ><STRONG>Source File:</STRONG></A> <EM>source-file</EM>
34 HREF="#ModuleIdentifier"
36 ><STRONG>Module Identifier:</STRONG></A> <EM>module-identifier</EM>
41 ><STRONG>Compatibility:</STRONG></A> <EM>compatibility notes</EM>
45 Each of the attributes, complete with values where possible, are
46 described in this document.
51 <LI><A HREF="#Status">Status</A>
53 <LI><A HREF="#SourceFile">Source File</A>
55 <LI><A HREF="#ModuleIdentifier">Module Identifier</A>
57 <LI><A HREF="#Compatibility">Compatibility</A>
62 <H2><A NAME="Status">Status</A></H2>
64 This indicates how tightly bound into the Apache Web server the
65 module is; in other words, you may need to recompile the server in
66 order to gain access to the module and its functionality. Possible
67 values for this attribute are:
70 <DT><STRONG>Base</STRONG>
72 <DD>A module labeled as having "Base" status is compiled
73 and loaded into the server by default, and is therefore normally
74 available unless you have taken steps to remove the module from your
79 <DT><STRONG>Extension</STRONG>
81 <DD>A module with "Extension" status is not normally
82 compiled and loaded into the server. To enable the module and its
83 functionality, you may need to change the server build
84 configuration files and re-compile Apache.
88 <DT><STRONG>Experimental</STRONG>
90 <DD>"Experimental" status indicates that the module is
91 available as part of the Apache kit, but you are on your own if you
92 try to use it. The module is being documented for completeness,
93 and is not necessarily supported.
97 <DT><STRONG>External</STRONG>
99 <DD>Modules which are not included with the base Apache
100 distribution ("third-party modules") may use the
101 "External" status. We are not responsible for, nor do we
102 support such modules.
109 <H2><A NAME="SourceFile">Source File</A></H2>
111 This quite simply lists the name of the source file which contains
112 the code for the module. This is also the name used by the <A
113 HREF="core.html#ifmodule"><CODE><IfModule></CODE></A>
118 <H2><A NAME="ModuleIdentifier">Module Identifier</A></H2>
120 This is a string which identifies the module for use in the <A
121 HREF="mod_so.html#loadmodule">LoadModule</A> directive when
122 dynamically loading modules. In particular, it is the name
123 of the external variable of type module in the source file.
127 <H2><A NAME="Compatibility">Compatibility</A></H2>
129 If the module was not part of the original Apache version 2
130 distribution, the version in which it was introduced should be listed
