override browser default with headers

Hi When a user is surfing from one page to another he don't reload the images every time unless a specific header is sent, which is good. My problem is when a user press on a form submit button that send the data & the user to a new page or even to the same, the Netscape/IE call a full refresh which is bad because all the images are reloaded. Can I send a header that will tell the netscape/IE not to do full refresh, the only thing that should be refreshed is the html file itself. -- -------------------------- Canaan Surfing Ltd.
