Executing webform from proxied page

[fbartolom]

Hullo, I would like to extract a number of links been triggered upon selecting the options of a webform. In order to test the behavior of it I copied the html of the page to my server and tried submitted the form but the correct link was not generated. I also tried adding a command but it went even worse. How may I pretend to be submitting a webform like I were on the original web server?
The page is:http://www.atm.it/it/Giromilano/Pagine/default.aspx and my copy is at: http://www.miafoto.it/iPhone/inarrivo/phpMi/form.html
the form to be submitted giving very different results is the second one with buses and trams.
Thanks
