Hi, When I begin session with session_start() PHP sets an Expired-header. I suppose that's fine for the sake of unwanted caching. Unfortunately, Firefox seem to reload a page that's expired when using the browser's "Back" navigation instead of showing the page as it was as the user left it. This seem to complicate some things. If I create a page with a form, the user submits it and press "back", the page is reloaded and the form is wiped instead of preserving the values as they were when the user submitted/left the page. I'm curious if there is a simple, acceptable workaround like disabling the Expires-header? I'm *not* looking for a solution where the session stores the form values and insert them into a value attribute. This won't work: 1. There is no way to distinct whether the user pushed "back" or clicked on a link to request the search page. The variables should be kept in the first situation but not in the second (and looking at the Referer header would be considered a hack as well). 2. Users can have multiple windows/tabs open which should not interfere with the navigation. It seems like Opera, Internet Explorer, links, lynx and w3m behave more reasonable. I believe that W3 also states that when using back buttons browsers should always show the page as when the user left it and not requesting it at new. Even if it is a bug in Firefox I would still like to know whether there is an acceptable workaround that would reduce the number of requests and make Firefox use the cached page (or cache the page in the first place). -- - Peter Brodersen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
