Changing Form Action

Hi, ASP.Net has a habit of putting its own action for the Form that runs at server...Every one knows that..But only few knows that this can be change with just simple code of Few lines... How? well we just need to intercept the Form tag rendering and put our own Action attribute simple.. Not clear than wait until i post more information on this .. Or Search MSDN for the same.. it has few tutorial on this..I don't have the Blog entry from where I found the solution but will post it soon.. Sumit Gupta
