If the page isn't the result of a post request -- that is, if your form method is GET -- it'll just reload from the server rather than throwing that error message. -----Original Message----- From: thelist-bounces at lists.evolt.org [mailto:thelist-bounces at lists.evolt.org] On Behalf Of VOLKAN ÖZÇELÝK > > If I select radio button "bar", submit the page, and then hit the back > button, "bar" is still active, not the off-screen "foo". > may be using no-cache headers and meta tags will sort it out.
