referer page is not good i think. because when the page is posted it is enlarged with the query string..isn't there a more accurate way to understand if the page is post back?

Strip the query string from the referrer URI then. Or use POST instead of GET, then we can talk about postbacks.

I don't know .Net so I don't know about the IsPosBack.

However , if you lookup HttpServletResponse here http://java.sun.com/javaee/5/docs/api/

there's a isCommitted method.

Perhas if response is committed on the the target page (the page which is in the action attribute of the form's post) then , isCommitted is set to true.

I havent tried this but it doesn't hurt if you experiment with it.

A postback is a form submit to self, not to another page.
