I'm at a complete loss... So I'm hoping someone can point me in the right direction to even start looking. We have an application written in PHP that lets users send out emails. The basic process is as follows. 1. Go to "start" screen. (This resets anything currently in process for the current logged in user) 2. Upload email addresses and other info (Names, etc) 3. Build Email 4. Send In Step 3 the user can click a "Live Preview" button to see what the email will look like with the merged data. Here's the problem, this works fine in all versions of IE, versions 1.5 or less of FireFox and versions 3 or less of Safari. However, starting in FireFox 2, and now Safari 4, when you get to step four OR click the live preview button in step three there is no more data in the merge. In those browsers the system is acting like the end user went BACK to the start page (in another window?) and reinitialized all the data. I immediately thought it might be pre-fetching so I tried using the system before and after toggling the network.prefetch-next setting in about:config with FireFox 2.0.0.20 and restarting the browser. No luck. So I added code to my reset function to email me the output of phpinfo() when the reset function is called. Using IE I get 1 notification. Using FF I get two notifications. This reinforces my theory that FireFox is prefetching the menu item to start a new mailing (just an <a> link...) from the top of the composer page. Even still... I've disabled prefetch so it SHOULDN'T even be considering those links right? I've also tried adding artificial "?now=<timestamp>" fakes to the end of all menu links since I read somewhere (don't remember where) that FireFox only prefetches pages with no query section in the address. Has anyone run into this behavior before? Any recommendations on how to stop it? Preferably from the server with code of some sort... Thanks in advance. Matt
