Re: cache design pattern
In general, "data" caching should happen at the data (model of MVC) layer.

RE: Cache problem
Hi,
An addendum to this problem.
What other cache are there apart from the browser cache. Tomcat server
cache ? Ways to disable it ? Our application has stopped dead in its tracks.
Thanks,

Subject: Cache problem
Hi,
I'm facing the following problem with the cache.
This is my javascript.
menu.addMenuItem("TCP vs. UDP vs.
ICMP","location='generic.action?report=21'");
1. This calls GenericAction and puts the report parameter in the session
and forwards to a JSP that displays some descriptive text.
This description JSP has the following
2. My web.xml has
nocache
true
Now my GenericAction is not called always when the menu is clicked. This has
caused severe problems.
What are we doing wrong here ? Is there a better solution for this ?
Appreciate any help.
Thanks,
Mohan

RE: Cache
Hi, If this is true then there is no way make sure that the struts action will be hit ? We show a description page that is just text. But the Generic forward action that forwards to description.jsp also takes a report ID and puts in the session. Sometimes the action wasn't fired because - we think - the browser picked it up from the cache. So the report ID became stale. So finally we used this The "-1" value - I don't have an explanation for that. The original value was "0". It worked. Maybe it will fail during rigorous testing.

Re: Cache
This works thanks. In order for it to work the user has to do a "Post" in the page then if you go to a different page and try to comeback the page will be expired, but what about if the user does not do anything on the page, or if the user hits a hyperlink, those two do not create a post, so if you go to a different page and hit the back button the page will be there. -Gus Kris Schneider wrote: For 1.0.2, set the servlet init param "nocache" to "true" Gus Delgado wrote: too late in the project to run that risk!!

Re: Cache
Yeah I tried adding this at the end of the action.
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Expires", "Wed, 26 Feb 1997 08:21:57 GMT");
I tested it but it does not seem to work on either IE or Mozilla

Is there any way to clean the cache from an Action. I have a
LogoutAction that gets all of the Attributes in the session by name
and removes all of them + it invalidates the session, but I also want
to clear the cache so that when the user hits the back button nothing
will be there.
Is there any way to do this?
-thanks
Gus

Re: Cache reload
hi, the init() function of a servlet is called only once, when the servlet class is loaded by the container. so, to achieve your periodic refresh, you may want to start a thread within the servlet container. IMHO that does not follow the spirit of the J2EE programming practices. A way we choosed for a commercial project was to have a daemon (in fact a RMI servant) which was acting as a periodicaly refreshed cache, but executing outside the servlet container, in its proper JVM. servlet (or web tier) can then communicate with the cache using RMI. for a smaller (or less distributed) project, I think I would do this rather by improving the accessors within the cache objet, in a way like this : when the getter (whichever it is) is called, it evaluates something like (now-last_time_i_refreshed), and if that's greater than the periodicity you need, the cache reload the appropriate values, and then return them to the caller. hope this helps. duf.
