Hi,
with the code below I can get netscape not to cache a jsp page but it
does not work with Internet-Explorer.
Does anybody know why?
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");\

Mac, or P
ol settings are
there to stop intermediate caches from falsely reporting a page as not
having changed.

I have the problem under Windows (I don't have Mac).
My goal is: when the user just comes back to a (JSP) page I want the
page executed again to show up to date information.

You could try having the JSP set its modified time to 'now', using a
java.util.Calendar object. That should cause the cache on the browser to
retrieve an updated copy of the page. I don't recall how to do this in
JSP land, but servlets do it by implementing getLastModified(), derived
from HttpServ

Failing that just tack a random number ( System.currentTimeMillis() ) onto

I do it from a JSP and not from a servlet and the page look like:

In looking over the HTTP/1.1 spec, the header to set is 'Last-Modified'. In
the spec documentation, though, they state that there's 60 seconds of slop
allowed, in the event that the browser and server clocks are out of sync.
Still, they say that if the cached copy differs from the server copy by t

OK,
Try telnetting to your box and issue the HTTP command:

I have always also used the expires header for dynamic pages.
My understanding is that this is the only header used by caching proxies for
determining whether or not to cache a page (aside from

Hi,
AFAIL, this doesn't work with some IE versions(5 and above I think) the
problem is caused because IE5+ decides whether it wonts to cache the
page if the page is greater than 32k. So, when it decides that the page
has to be cached, the headers have been long ago forgotten :(. The
