<H2>Summary</H2>
-<p>This is an experimental module. On selected operating systems it
-can be used to load modules into Apache at runtime via the <A
-HREF="../dso.html">Dynamic Shared Object</A> (DSO) mechanism, rather
-than requiring a recompilation.
+<P>On selected operating systems this module can be used to load modules

<P>
On Unix, the loaded code typically comes from shared object files
-(usually with <SAMP>.so</SAMP> extension), whilst on Windows this
-module loads <SAMP>DLL</SAMP> files. This module is only available in
-Apache 1.3 and up.

+the <SAMP>.so</SAMP> or <SAMP>.dll</SAMP> extension. This module is
+only available in Apache 1.3 and up.
<p>In previous releases, the functionality of this module was provided
for Unix by mod_dld, and for Windows by mod_dll. On Windows, mod_dll
was used in beta release 1.3b1 through 1.3b5. mod_so combines these
two modules into a single module for all operating systems.
+<P><STRONG> Warning: Apache 1.3 modules cannot be directly used with
+ Apache 2.0 - the module must be modified to dynamically load or
+ compile into Apache 2.0</STRONG>.</P>

+<P><STRONG>Note: the module name format changed for Windows with Apache
+ 1.3.15 and 2.0 - the modules are now named as mod_foo.so</STRONG>.
+ While mod_so still loads modules with ApacheModuleFoo.dll names, the
+ new naming convention is preferred; if you are converting your loadable
+ module for 2.0, please fix the name to this 2.0 convention.</P>
<P>The Apache module API is unchanged between the Unix and Windows
versions. Many modules will run on Windows with no or little change
<P>To create a module DLL, a small change is necessary to the module's
source file: The module record must be exported from the DLL (which
- will be created later; see below). To do this, add the
- <CODE>MODULE_VAR_EXPORT</CODE> (defined in the Apache header files) to
- your module's module record definition. For example, if your module
+ will be created later; see below). To do this, add the <CODE
+ >AP_MODULE_DECLARE_DATA</CODE> (defined in the Apache header files)
+ to your module's module record definition. For example, if your module
has:</P>
<PRE>
module foo_module;
</PRE>
<P>Replace the above with:</P>
<PRE>
- module MODULE_VAR_EXPORT foo_module;
+ module AP_MODULE_DECLARE_DATA foo_module;
</PRE>
<P>Note that this will only be activated on Windows, so the module can
continue to be used, unchanged, with Unix if needed. Also, if you are
record with that method instead.</P>
<P>Now, create a DLL containing your module. You will need to link this
- against the ApacheCore.lib export library that is created when the
- ApacheCore.dll shared library is compiled. You may also have to change
+ against the libhttpd.lib export library that is created when the
+ libhttpd.dll shared library is compiled. You may also have to change
the compiler settings to ensure that the Apache header files are
- correctly located.</P>
+ correctly located. You can find this library in your server root's
+ libexec directory. It is best to grab an existing module .dsp file
+ from the tree to assure the build environment is configured correctly,
+ or alternately compare the compiler and link options to your .dsp.</P>
<P>This should create a DLL version of your module. Now simply place it
in the <SAMP>modules</SAMP> directory of your server root, and use
to the list of active modules. <EM>Module</EM> is the name of the
external variable of type <CODE>module</CODE> in the file, and is
listed as the <a href="module-dict.html#ModuleIdentifier">Module
-Identifier</a> in the module documentation. Example (Unix):
