+
+==== Mapping Static Resources ====
+
+Out of the box, Trac will pass static resources such as style sheets or images through itself. For anything but a tracd only based deployment, this is far from optimal as the web server could be set up to directly serve those static resources (for CGI setup, this is '''highly undesirable''' and will cause abysmal performance).
+
+Web servers such as [http://httpd.apache.org/ Apache] allow you to create “Aliases” to resources, giving them a virtual URL that doesn't necessarily reflect the layout of the servers file system. We also can map requests for static resources directly to the directory on the file system, avoiding processing these requests by Trac itself.
+
+There are two primary URL paths for static resources - `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible by `/chrome/<plugin>` path, so its important to override only known paths and not try to make universal `/chrome` alias for everything.
+
+Note that in order to get those static resources on the filesystem, you need first to extract the relevant resources from Trac using the [TracAdmin trac-admin]` <environment> deploy` command:
+[[TracAdminHelp(deploy)]]
+
+The target `<directory>` will then contain an `htdocs` directory with:
+ - `site/` - a copy of the environment's directory `htdocs/` 
+ - `common/` - the static resources of Trac itself
+ - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
+
+===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
+
+Assuming the deployment has been done this way:
+{{{
+$ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
+}}}
+
+Add the following snippet to Apache configuration ''before'' the `ScriptAlias` or `WSGIScriptAlias` (which map all the other requests to the Trac application), changing paths to match your deployment:
+{{{
+Alias /trac/chrome/common /path/to/trac/htdocs/common
+Alias /trac/chrome/site /path/to/trac/htdocs/site
+
+<Directory "/path/to/www/trac/htdocs">
+  Order allow,deny
+  Allow from all
+</Directory>
+}}}
+
+If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
+{{{
+<Location "/trac/chrome/common/">
+  SetHandler None
+</Location>
+}}}
+
+Note that we mapped `/trac` part of the URL to the `trac.*cgi` script, and the path `/trac/chrome/common` is the path you have to append to that location to intercept requests to the static resources. 
+
+Similarly, if you have static resources in a project's `htdocs` directory (which is referenced by `/trac/chrome/site` URL in themes), you can configure Apache to serve those resources (again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation):
+{{{
+Alias /trac/chrome/site /path/to/projectenv/htdocs
+
+<Directory "/path/to/projectenv/htdocs">
+  Order allow,deny
+  Allow from all
+</Directory>
+}}}
+
+Alternatively to aliasing `/trac/chrome/common`, you can tell Trac to generate direct links for those static resources (and only those), using the [[wiki:TracIni#trac-section| [trac] htdocs_location]] configuration setting:
+{{{
+[trac]
+htdocs_location = http://static.example.org/trac-common/
+}}}
+Note that this makes it easy to have a dedicated domain serve those static resources (preferentially [http://code.google.com/speed/page-speed/docs/request.html#ServeFromCookielessDomain cookie-less]).
+
+Of course, you still need to make the Trac `htdocs/common` directory available through the web server at the specified URL, for example by copying (or linking) the directory into the document root of the web server:
+{{{
+$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
+}}}

 == Configuring Authentication ==
 
-The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac. The basic procedure is described in the [wiki:TracCgi#AddingAuthentication "Adding Authentication"] section on the TracCgi page. To learn how to setup authentication for the frontend you're using, please refer to one of the following pages:
-
- * TracStandalone if you use the standalone server, `tracd`.
- * TracCgi if you use the CGI or FastCGI web front ends.
- * [wiki:TracModWSGI] if you use the Apache mod_wsgi web front end.
- * TracModPython if you use the Apache mod_python web front end.

-== Automatic reference to the SVN changesets in Trac tickets ==
+Trac uses HTTP authentication. You'll need to configure your webserver to request authentication when the `.../login` URL is hit (the virtual path of the "login" button). Trac will automatically pick the REMOTE_USER variable up after you provide your credentials. Therefore, all user management goes through your web server configuration. Please consult the documentation of your web server for more info.
