[W3af-users] Launch scan after form submit

[Luigino <ar...@gm...>]

Hello all,
I'm a newbie. I'm making test for learn w3af.
I want to create a form in a website with a field for send an url. 
My goal is to perform a w3af scan against the url received from the form.
I can't found any resources about it. 
Can someone give a little help?
Thank you in advanced.
