"...you sometimes receive old content after having received new content..."

That is EXACTLY what I'm getting...and it could be any version in between! I'm not sure on the proxy servers, but I doubt it. As far as I know this is a basic intranet server. I need to hear back from the guy that does the network architecture to know for sure...

I guess I should have been clearer on what I am getting. When I modify my HTML templates, the output is immediately correct. When I modify my perl script, I have to refresh several times to maybe see the change. ...and once I do see the change, I may get the older version at any time. The portion that is generated with the perl is seemingly random. Some crazy examples:

• Now-fixed errors getting generated & triggering a separate error page (in the perl) to display instead of the correct output page
• Email generation: either triggered by the example above and/or containing different content than the current version
• SQL queries & output may be different -- including now-fixed SQL errors still being generated, ex. incorrect server connection variables, query typos, etc
• Different variable values presented to the templates

I suppose the last 2 examples could be a previously cached local version, but to me the email screams "server problem". Frustrating, to say the least.

I haven't checked the access logs, but when I receive an error, it's in the error logs and of course the email error is generated. I can check the access log, of course it may take me a while to PURPOSELY recreate the problem!

...Yes, I've tried the ctrl+f5, clearing my cache multiple times, changing browser settings, blah blah blah, and anything else that would point to a local caching problem... I can also recall having end users test it for me that have NEVER been to the page, however they may get a previous version.

I just scanned those links you referred and haven't read them in depth yet, but wouldn't controlling the caching in the HTTP headers only effect the HTML and not the perl behind the scenes?
