> processNoCache() method does not expire properly.
> The Cache-Control header is set by processNoCache() method in RequestProcessor
> as follows:
> response.setHeader("Cache-Control", "no-cache");
> With IE everything is fine. Hitting the back button works wonderfully and if
> the
> previous request was a GET it would be "re GOTTEN" and if it was a POST, it
> displays the "POST data has expired warning. U wanna resubmit?" dialog.
> However, for some other browsers, it doesn't quite work.
> In Galeon and mozilla, regardless of whether the HTTP request was a POST or a
> GET, hitting the back button shows the previous screen in its original glory
> (not good).
> I made a slight tweak and over-rode the processNoCache() method in "my
> RequestProcessor" (which incidentally overrides TilesRP). Inside this
> overriddent, I changed the Cache-Control setting to:
> response.setHeader("Cache-Control",
> "no-cache,no-store,max-age=0");
> After this IE, galeon, mozilla, netscape 7, all were correctly either
> re-GETting
> the GET request or posting a warning about re-POSTing the POST request when
> the
> back button was hit.
> Could this modification be made directly in
> src/share/org/apache/struts/action/RequestProcessor.java, please? I don't see
> any side-effects (yet :-)).
> I see from the annotation history that this line has been in this file since
> the
> intial commit (2 years, 3 months ago) done by craigmcc. Craig, do you have any
> thoughts?
