Even proxies seem to respect that rule and do not cache the page if the method was a POST. If you are sending non critical data and the volume is small you might want to consider a switch from POST to GET for some of the pages at least. all the best Tim Winters wrote: >Hello, > >I have a series of forms set over a few pages.
