Proxy servers and the main site

@doom9

Proxy servers don't seem to be handling the main site very well - I get served stale content that is usually 10-30 days old - even when hitting the refresh button. (The forums work fine).

I haven't examined the headers that are served off the main site, but I usually fix this by placing a "paragma nocache" and/or "content expires" in the HTTP header to keep proxies from caching the pages.

You wouldn't know how this translates into the httpd.conf file, would you? By now I only have Apache servers (but both 1.x and 2.x)

Actually, no-cache is simply this:
<head><http-equiv="pragma" content="no-cache"></head>

...and both Apache and PHP have a way to automatically add them to the served document's header.

The line item CacheNegotiatedDocs in the httpd.conf file should be commented, thus add the Pragma: no-cache to the HTTP header.

PHP by default also adds data to the header to prevent proxy caching, which is probably why the forums works.

If this value is presently commented, I'll stick an HTTP sniffer on my network and see what the headers are showing.
