CGI

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'sAppEngine [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] 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.
