Do not cache
Is there a way to force a page to not be cached. The page contains some dynamic data from a database which should never be cached. This needs to work for Netscape 4.0+ and IE 4.0+
Thanks, RickH

Haha, punker, maybe? Maybe yes, both can be used (or must be used) ;). Though you might also wanna add this
<META HTTP-EQUIV="Expires" CONTENT="Fri, Jun 22 1990 10:30:00 GMT">
So you'll need these three things in your page in the <head> tags and things should be solved.

I don't know. I tried using these on a CF page, and they didn't work. I know they're meant to work, but in my experience, they do nill.
mmmm, interesting....I'll check it out...
I have the same problem when using location.href='mypage.htm'

FYI, I am doing this in Cold Fusion also.

Rick: In that case, it will not reload the data on the page to reflect changes unless you surf to the page a second time or hit reload. That's my experience with it.
Try attaching a unique querystring to the url, even if it does not do anything. It will force a cache.
i.e. in ASP you can do:
<%
TimeStamp = Now
%>
:
<a href='something.htm?Timest
Works for me.

I have placed suggestions for site visitors to set their browser to check for a new page everytime.
In IE5 this is in the "Tools" menu, "Internet Options", "General" tab, "Temporary Internet Files", "Settings" button. Under "Check for New Versions of Stored Pages" have the "Every Visit to the Page" radio button selected.
In Netscape 4.7 this is under "Edit", "Preferences", "Advanced", "Cache", then on the right side of the box, under "Document in cache is compared to document on network" choose the radio button labeled "Every Time".
I realize that it is less desireable than setting up the page for no cache, but the user will benefit by getting newest pages always.

or
<META http-equiv="Cache-Control"
The first one is used commonly. The second one came from a book I have, and I'm not too sure about it.
