Just to extend to this idea, the way my apps handle get and post 
requests are different methods within the page class, I have still 
gotta get around the validate issue where its limited to post to itself 
but cant be seperated in get and post methods.

What I am going to attempt to do, is create a client side handle check 
which does an ajax connection to a handle check service and return 
either true or false :) My only concerns of this is browsers that can 
support ajax.
