Forum Caching Too Well

[Kaisan]

I'm running two installations of vBulletin on my server but for some reason, one of them is caching too much. Every user has to hit refresh each time they want to see if the index or a thread has been updated. Clicking a link will just show what the browser cached last time.

The strange thing is, I have another installation of vBulletin with near identical config.php settings but that one doesn't encounter this problem. I've tried disabling xcache etc but it's done nothing (besides, it's not causing a problem on the other installation).

Does anyone know what to do?

Thanks.

Check the .htaccess for each site. I'll bet there is some caching going on in there.

The .htaccess files were different so I made them identical. Unfortunately that didn't change anything. Besides, they were just rewrite instructions

Are you using a different xcache prefix for each installation?

do you have different rules in the httpd.conf file for each installation? Look for something that has to do with mod_expires or mod_headers.

I figured out the issue. It was a higher up .htaccess causing the problem. A caching Wordpress plugin decided to force the entire site to follow it's rules rather than just the Wordpress installation. It also seems like it's impossible to exempt certain directories from it. Oh well. Disabled that and now things are working fine. Thanks for the help!

Glad you got it figured out.
