| | A suggestion. Don't know if it's just the proxy at work or what but very often when I go to read the forum from there I am forced to do a reload several times to convince it that I want to see current data. It will often be holding some very stale copies in the cache. Maybe a no-cache header or something would solve this? It doesn't happen when I'm at home and not using a proxy. | | Top |

| | I'm not sure I can influence the HTTP headers. I don't notice the problem myself. Might be an aggressive proxy server that re-serves up the same page even when you hit refresh. |

| Yeah, that's what I'm thinking too, but I can't exactly go to the proxy admins and ask them to knock it off either :P
You might want to look into this:
http://us2.php.net/manual/en/function.header.php
Has some information that looks relevent, including an example of a no-cache header directive. | | Top |

| OK, I added this to the header:
Cache-Control: no-cache, must-revalidate
See if that works better. :) |
