Hi Lucas,
Although this is a very nice and well known project, and don't think this is "exactly" what Massimo needs.
Hi Massimo,
Please try method server->request->get_form_fields( ), for all parameters, or server->request->get_form_field( ) for a single parameter. Yes, I know, its name is misleading, but should solve your problem.
Another way is to use server->request->get_header_field( '~request_uri' ) and then split the values manually. First method would be easier though.
Cheers,
Custodio
