Colin,
Dave is spot on with his recommendation. IE is particularly bad about
caching content even when it's not supposed to such as within https
sessions. Use thse cache headers that Dave specified and IE will stop
caching. I have found that I only need the following but Dave's
suggested headers will clearly due the trick.
response.setHeader("Cache-Control", "max-age=0, must-revalidate");
Carson

https in *IE*.
Indeed he is! :-)
However... with regard to the fix, I seem to have spoken to quickly.
Although adding the FormAuthenticator valve fixed the immediate
problem I was experiencing, it seems to also cause other issues
(again, this only appears on IE).
My application has a polling thread that periodically calls a specific
URL. With the FormAuthenticator valve enabled, the behaviour
'appears' to be that the HTTPService is called, the response handler
is fired, but *the server never receives a request*.
What makes it even stranger is that the response handler has a valid
response definition.
My hunch is that setting the disableProxyCaching=false is working
against me in this case and only the first call is ever making it to
my servlet.
Make sense? Any thoughts?
