Description:Maps a URL to a filesystem location and designates the target as a WSGI script.
Syntax:WSGIScriptAliasMatch regex file-path|directory-path
Context:server config, virtual host

This directive is similar to the WSGIScriptAlias directive, but makes use of regular expressions, instead of simple prefix matching. The supplied regular expression is matched against the URL-path, and if it matches, the server will substitute any parenthesized matches into the given string and use it as a filename.

For example, to map a URL to scripts contained within a directory where the script files use the .wsgi extension, but it is desired that the extension not appear in the URL, use:

WSGIScriptAliasMatch ^/wsgi-scripts/([^/]+) /web/wsgi-scripts/$1.wsgi

Note that you should only use WSGIScriptAliasMatch if you know what you are doing. In most cases you should be using WSGIScriptAlias instead. If you use WSGIScriptAliasMatch and don’t do things the correct way, then you risk modifying the value of SCRIPT_NAME as passed to the WSGI application and this can stuff things up badly causing URL mapping to not work correctly within the WSGI application or stuff up reconstruction of the full URL when doing redirects. This is because the substitution of the matched sub pattern from the left hand side back into the right hand side is often critical.

If you think you need to use WSGIScriptAliasMatch, you probably don’t really. If you really really think you need it, then check on the mod_wsgi mailing list about how to use it properly.
