+
+[http://code.google.com/p/modwsgi/ mod_wsgi] is an experimental Apache module for running WSGI-compatible Python applications directly on top of Apache:
+
+  The mod_wsgi adapter is an Apache module that provides a WSGI compliant interface for hosting Python based web applications within Apache. The adapter is written completely in C code against the Apache C runtime and for hosting WSGI applications within Apache provides significantly better performance than using existing WSGI adapters for mod_python or CGI.
+
+It is already possible to run Trac on top of mod_wsgi. This can be done by writing the following application script.
+
+{{{
+import os
+
+os.environ['TRAC_ENV'] = '/usr/local/trac/mysite'
+os.environ['PYTHON_EGG_CACHE'] = '/usr/local/trac/mysite/eggs'
+
+import trac.web.main
+application = trac.web.main.dispatch_request
+}}}
+
+The {{{TRAC_ENV}}} variable should naturally be the directory for your Trac environment (if you have several Trac environments in a directory, you can also you {{{TRAC_ENV_PARENT_DIR}}} instead), while the {{{PYTHON_EGG_CACHE}}} should be a directory where Python can temporarily extract Python eggs. For clarity, you should give this file a {{{.wsgi}}} extension. You should probably put the file in it's own directory, since you will open up it's directory to Apache.
+
+After you've done this, add the following to your httpd.conf.
+
+{{{
+WSGIScriptAlias /trac /usr/local/trac/mysite/apache/mysite.wsgi
+
+<Directory /usr/local/trac/mysite/apache>
+    Order deny,allow
+    Allow from all
+</Directory>
+}}}
+
+Here, the script is in a subdirectory of the Trac environment. In order to let Apache run the script, access to the directory in which the script resides is opened up to all of Apache. Restart Apache, and then it should work.

+See also the mod_wsgi [http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac installation instructions] for Trac.
