I use a RequestFilter instead of a dispatcher to achieve same thing... but it
should work just the same for you (before:PageRender is fine). In your
dispatcher you need to check your state object for null and redirect to your
login page.
For example:
if(applicationStateManager.get(SiteSessionAccess.class) == null){
response.sendRedirect(loginPage);
return true;
}
Short-circuits the page load.

Subject: T5: how to detect session timeout?
Hi,
I am trying to deal with session timeouts in T5.
Rather than extend a base class I was hoping I might be able to use an
Annotation. However, I find that when the user activates a link or
presses a button on a timed-out session that the dispatcher is not
being called early enough to detect anything and I end up with a null
pointer exception.
I have the following in my AppModule:
configuration.add("TimeoutDetector", timeoutDetector,
"before:PageRender");
Two questions:
a) is it possible to detect Session timeouts in this way?
b) As PageRender isn't early enough can I hook this in earlier? I'd
also appreciate knowing what values can be placed in that parameter.
Nowhere can I find this documented (apart from a reference to
"before:" and "after:"). I've even looked in the T5 code but I'm
afraid there is just too much of it to look through. Surely the
specification of part of a page lifecycle would be better as something
other than a String?!
thanks,
p.
