# CGI If all other deployment methods do not work, CGI will work for sure. CGIis supported by all major servers but usually has a less-than-optimalperformance. This is also the way you can use a Werkzeug application on Google's[AppEngine](http://code.google.com/appengine/) [http://code.google.com/appengine/], there however the execution does happen in a CGI-likeenvironment. The application's performance is unaffected because of that. ### Creating a .cgi file First you need to create the CGI application file. Let's call ityourapplication.cgi: ~~~ #!/usr/bin/python from wsgiref.handlers import CGIHandler from yourapplication import make_app application = make_app() CGIHandler().run(application) ~~~ If you're running Python 2.4 you will need the [wsgiref](http://docs.python.org/dev/library/wsgiref.html#module-wsgiref "(在 Python v3.5)") [http://docs.python.org/dev/library/wsgiref.html#module-wsgiref] package. Python2.5 and higher ship this as part of the standard library. ### Server Setup Usually there are two ways to configure the server. Either just copy the.cgi into a cgi-bin (and use mod_rerwite or something similar torewrite the URL) or let the server point to the file directly. In Apache for example you can put a like like this into the config: ~~~ ScriptAlias /app /path/to/the/application.cgi ~~~ For more information consult the documentation of your webserver.
