Best Method for forcing "no-cache"

[Elwin]

My users complain that they don't get to see my latest updates of the website. It is important that the new pages are available for viewing when uploaded to the server. I realize that the problem is that these pages are cached on the users' systems and that their browsers are set to serve up the older, cached pages rather than the current ones. I also understand that there are various ways that I can force a refresh from my HTML code, i.e. "Pragama, No-Cache" metatag, and others. Haven't tried any yet - looking for some advice.

Any suggestions on which method will work best? I would like to keep it as simple as possible.

Thanks in advance

Every browser understands different methods, so the best way to do it is with multiple methods. I used to have a site bookmarked that had what seemed to be a good mix, but I can't find it now. I'll keep looking.

Depends on what HTTP protocol version is used. Try:
Hypertext Transfer Protocol -- HTTP/1.1

Specifically, review Caching in HTTP and Cache-Control under Header Field Definitions. It's a bit intimidating at first but it does describe very specifically how user agents should respond to requests and the different ways of sending the proper headers and their formats.
