how to know what page or call is being when in a JSP page when submited
The developers console ( F12 in Chrome and Firefox) is a wonderful thing. 
Check the Network or Net tab. There you can see all the requests between your browser and your server.
I have a JSP page called X.JSP (contains few radio button and submit button), when i hit the submit button in X.JSP, the next page is displayed Y.JSP?xxxx=1111&yyyy=2222&zzzz=3333

how to know what page or service or ajax call is being made when i hit the submit button in X.JSP page.
xxxx=1111&yyyy=2222&zzzz=3333 these are generated after i click the submit button in X.JSP

Currently i am using python to script.
i select a radio button and post the form. i am not able to get the desired O/P.
how do I what page or service or ajax call is being made when i hit the submit button in X.JSP page, so that i can directly hit that page
or is there any better way to solve this
