mod_wsgi WSGIScriptAlias directive ¶
The WSGIScriptAlias directive behaves in the same manner as the Directive Alias (module mod_alias) directive, except that it additionally marks the target directory as containing WSGI scripts, or marks the specific file-path as a script, that should be processed by mod_wsgi’s wsgi-script handler.
Where the target is a directory-path, URLs with a case-sensitive (%-decoded) path beginning with URL-path will be mapped to scripts contained in the indicated directory.
WSGIScriptAlias /wsgi-scripts/ /web/wsgi-scripts/
A request for http://www.example.com/wsgi-scripts/name in this case would cause the server to run the WSGI application defined in /web/wsgi-scripts/name.
This configuration is essentially equivalent to:
Alias /wsgi-scripts/ /web/wsgi-scripts/ <Location /wsgi-scripts> SetHandler wsgi-script Options +ExecCGI </Location>
Where the target is a file-path, URLs with a case-sensitive (%-decoded) path beginning with URL-path will be mapped to the script defined by the file-path.
WSGIScriptAlias /name /web/wsgi-scripts/name
A request for http://www.example.com/name in this case would cause the server to run the WSGI application defined in /web/wsgi-scripts/name.
If possible you should avoid placing WSGI scripts under the DocumentRoot in order to avoid accidentally revealing their source code if the configuration is ever changed.
The WSGIScriptAlias makes this easy by mapping a URL and designating the location of any WSGI scripts at the same time.
If you do choose to place your WSGI scripts in a directory already accessible to clients, do not use WSGIScriptAlias.
Instead, use <Directory>, SetHandler, and Options as in:
<Directory /usr/local/apache/htdocs/wsgi-scripts> SetHandler wsgi-script Options ExecCGI </Directory>
This is necessary since multiple URL-paths can map to the same filesystem location, potentially bypassing the WSGIScriptAlias and revealing the source code of the WSGI scripts if they are not restricted by a Directory section.
