Hello,

A page with its response header as:

(Status-Line)   HTTP/1.1 200 OK
Cache-Control   no-cache
Connection      keep-alive
Content-Type    text/html; charset=UTF-8
Date    Mon, 14 Feb 2011 11:11:09 GMT
Expires Mon, 14 Feb 2011 11:11:08 GMT
Pragma  No-cache
Server  nginx/0.8.54
Transfer-Encoding       chunked

The page is dynamic, different user should see different content.
But the URL is always the same.

When content varies on user account the content is "private" and should be marked as such in Cache-Control.

When content is not supposed to be stored by caches it need to be marked "no-store"

"no-cache" is a slightly fuzzy middle ground which is treated differently by all browsers and caches. As well as differently when sent on request and response. It is allowed to be stored and shared around, but has to be revalidated with the origin before use.



Firefox/IE8/Chrome goes without problem.
But IE7 (and other IE below it I believe) have been caching this page,
for different people the see the same content.
Once they press "F5" to refresh the page all goes well.

Is this an IE problem? how to prevent the (broken?) IE caching it?

Interesting results. Thank you for mentioning this problem.

Using "private" or "no-store" as appropriate for your content should fix this problem for all browsers.
