-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 use {{{TRAC_ENV_PARENT_DIR}}} instead), while the {{{PYTHON_EGG_CACHE}}} should be a directory where Python can temporarily extract Python eggs.

+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 use `TRAC_ENV_PARENT_DIR` instead), while the `PYTHON_EGG_CACHE` should be a directory where Python can temporarily extract Python eggs.
+
+'''Important note:''' If you're using multiple `.wsgi` files (for example one per Trac environment) you must ''not'' use `os.environ['PYTHON_EGG_CACHE']` to set the path to the Trac environment. Using this method may lead to Trac delivering the content of another Trac environment. (The variable may be filled with the path of a previously viewed Trac environment.) To solve this problem, use the following `.wsgi` file instead:
+
+{{{
+#!python
+import os
+
+os.environ['PYTHON_EGG_CACHE'] = '/usr/local/trac/mysite/eggs'
+
+import trac.web.main
+def application(environ, start_response):
+  environ['trac.env_path'] = '/usr/local/trac/mysite' 
+  return trac.web.main.dispatch_request(environ, start_response)
+}}}
+
+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 its directory to Apache. You can create a .wsgi files which handles all this for you by running the TracAdmin command `deploy`.
 
 If you have installed trac and eggs in a path different from the standard one you should add that path by adding the following code on top of the wsgi script:
+
 {{{
+#!python
 import site
 site.addsitedir('/usr/local/trac/lib/python2.4/site-packages')
 }}}
+
 Change it according to the path you installed the trac libs at.
