Getting posted parameter from headers

Getting posted parameter from headers

Hi all,

Firebug's console is showing when visiting my test.html page Headers, Post and Response.
In the Post tab it is showing: "id 9"

I need to create a new page and get that 9 in it so I can use it. I don't mind jQuery, Ajax or Javascript but I need that 9.

I know that with php I just need $_REQUEST["id"]; but I cannot use php.

Thanks a lot in advance!!
