Problem with HTTP Get request parameters and Facebook

Question

Hi,

I need to send a GET request from a Facebook canvas application to an external URL. I'm using cURL to send the request.

It seems like Facebook ignores the parameters of the GET request, except the first one. Say I have: http://url.com/page.php?param1=value1&param2=value2&param3=value3.

The script page.php should write value1, value2 and value3 in a database, and in fact it does if I call it from the browser's address bar, but not if I send the request via Facebook, when it only writes value1.

Has anybody had this issue too, or know how to solve it?

Thank you!
