Can i call filter after particulate event?

[mallikarjun dontamsetti]

Hi can i call a filter after a event, say i have a logout link and it is redirecting to lo-gout servlet where i am removing all session attributes like this

HttpSession session= request.getSession();
Enumeration  e = session.getAttributeNames() ;
while(e.hasMoreElements() ){
  String key = e.nextElement() .toString();
  session.removeAttribute(key);
}

session.invalidate() ;

//Now i want here to call a filter which remove all cache of my JSP, Servlets..

responce.sendRedirect("index.jsp");

is that possible or any why to clear cache after logout link is pressed..

You don't call filters -- they are automatically invoked to bracket mapped requests. Why do you need to call a filter? Just refactor the code so that it can be called as a method.

i want to clear all jsp cache after logout. if i use methode is it clear all my JSP cache?

[Paul Clapham]

It appears to me that your question is actually "How do I clear my JSP cache (whatever that is) from Java code in a servlet or filter?" Is that right?

[mallikarjun dontamsetti]

yes correct

You could have the same logic within a method to clear your JSP, servlets cache when you wanted to do so. Actually by calling appropriate session.invalidate(), will clear all session stored items for a particular session.

[Bear Bibeault]

The session has nothing at all to do with the cache, so invalidating the session will have no effect not he cache.

See the ServletsFaq for information on setting cache headers.

You can configure filters to intercept request/responses before reaching/coming from the servlet. So, upon clicking "logout" it is expected to go to servlet and you can configure a filter before it goes to the actual servlet.

But this has nothing to do with clearing cache. As Bear pointed out, you need to refer the link he provided.
