How to create an form info and send this POST?

some page use js or ajax to construct an form and make a POST. GSA can do such thing?  post data seem only construct the form info but how to POST to action url? how to set this ?

have a look on the new MacOSWiki engine. That "simulates" the whole process done by ajax/jc.

ajax is not issue, my question is how to POST method to a url because there is no form.  after check MacOSWiki, i set below:

[register_step3]
modify url=http://form-action-url.com
post data= 

it just GET http://form-action-url.com  How to POST method to http://form-action-url.com?  is there any key i need to set?

don't forget the "just download=1"

so put just download to make GET to POST method right? it is a bit wired,isn't it? it just a trick?

whats weird on that?

modify url + post data + just download...I don't see any weirdness in this.

just download means only GET and not POST right? or i miss something? or it mean only one http GET/POST?

just download means not to search for forms to post to. if post_data is empty it uses GET, else POST

see,  some site use POST but post data=empty.  how to do then?

POST without any post data is not a valid method and I have never seen such thing.

squidoo now use ajax do it. please confirm it.

but a POST request without post data is a GET request.

by http tool, it do show as POST method.

if  there are post data, and NO just download, it will use form + post data to submit?  or just use one of them? which one?

Without "just download=1" it will first open that URL and try to find a form thats suitable and most likely fail if you didn't define one.
