Internet Explorer caching issue

[CaroleR]

I have a website that offers a service to subscribed members. It has been reported to me that one of the pages that has a form used to submit data to a mysql database has not been displaying saved changes.The form should display back data that has been stored in the database. (After the page has been submitted)I thought this was odd, as I was under the impression that php pages could not be cached.I have tried using:\[code\]header("Cache-Control: no-cache");header("Expires: -1");\[/code\]and private mode in IE8 but this made no difference.This problem does not occur when using any other browser other than Internet explorer 6/7/8Any help would be greatly appreciated.
