Hello all. I'm maintaining a site for a client that is having a convention for a week. During that week, we will have each days agenda online and then as those events happen (speeches, presentations, etc.) those events will be viewable online. The problem is though that people who come to the site multiple times always see the original version of the page. I have to instruct them to click refresh in their browser window to see any recent changes/additions to the page. Sometimes that doesn't even do it. They have to do a "force refresh" (ctrl+F5). Anyways, rather than explaining all this on the web page, is there a way to just have a link that says "Refresh Page" and when they click on it, it will do a force refresh. Or, is there a better way to accomplish this?? Any help is appreciated.

You can do this with a JavaScript link. Here's the code to do it:

Thanks a ton bhartzer.
I noticed on PCs sometimes even after clicking the refresh button that you are still seeing the old version. People would have to click alt+refresh. Would I come across this same problem with your refresh link?

This refresh code essentially does the same thing as the alt+refresh. It just makes it easier and puts it in the forum of a link.
Keep in mind that there are a lot of ISPs out there (even major ones like Comcast and Earthlink) that cache pages on the ISP level and not the browser level. So, the users aren't able to refresh the page even though their browser refreshes the page. There's nothing you can do about that.
Another thing you can do is put the no cache code on the page to try and stop the web browser from caching the page at all so you don't run into anyone having to refresh the page.

What would that code be? Does it work across all browsers?

To stop a browser from caching you'll have to read this.
Or, if you want, just do this search and look for it.
