Hi and thank you for your time in advance,

My question is I have a folder /folder-name/ on my server and we change the index.html file in here regularly but for some older browsers and clients they never get the updated information because the old information is cached in their old browser. So I have used this tactic:

[How to control web page caching, across all browsers?](https://stackoverflow.com/questions/49547/making-sure-a-web-page-is-not-cached-across-all-browsers)

But it doesn't work all the time. My idea was to change the file to something different (using date so its unique) and whenever anyone goest to that folder it just defaults to show whatever HTML file is in there. This way the browser would refresh the cache thinking it is a new page each time. 

So when the user goes to www.domain.com/folder-name/ it just loads whatever HTML file is in there.

Thanks again for your time.

And what happens is certain users (older IE browsers) are caching the schedule and people call in saying they are seeing a schedule 6 months ago. I can't recreate the issue but we get about 5-10 calls a month.
