# Werkzeug

# CGI

If all other deployment methods do not work, CGI will work for sure. CGI is supported by all major browsers but usually has a less-than-optimal performance.

This is also the way you can use a Werkzeug application on Google’s AppEngine, there however the execution does happen in a CGI-like environment. 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 it yourapplication.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` package. Python 2.5 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 to rewrite 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:

    ScriptName /app /path/to/the/application.cgi

For more information consult the documentation of your webserver.
