Programmatically log on to a site

I am not sure if this fits better on StackOverflow, but here goes:

I want to programmatically log on to:

http://wrds开发者_如何学运维-web.wharton.upenn.edu/wrds/index.cfm?true

I tried capturing the log on url using fiddler2 and HttpFox, but to no avail.

Is this a server side script that I cannot capture? If so how can I do the log on?

You won't see a "login URL" because the form uses the POST method. The method you will need to use depends on the language. In Python, you could use urllib for example.
