+=== Python Egg Cache

+The [TracInstall#egg-cache egg-cache] can be configured using an `os.environ` statement in `trac.cgi`, as shown above.
+To do the same from the Apache configuration, use the `SetEnv` directive:
+{{{#!apache
+SetEnv PYTHON_EGG_CACHE /path/to/dir
+}}}

+Put this directive next to where you set the path to the [TracEnvironment Trac environment], i.e. in the same `<Location>` block.
