Re: Change URL location on CURL requests?

Hi Alessandra,

Try setting the CURLOPT_REFERER option to the form URL. Some form handler
check for this value believing that it would prevent form spoofing (and it
clearly doesn't). If that doesn't work, then I guess you'll have to show us
the forms in question so that we can help you further.

With regards,
