James... dont know... couple of thing you can do... get wire shark and 
actually watch whats on the wire... if the header is coming in and no body 
is sent, it aint tomcat...
My Ajax is stale... if you doing it yourself, then its very like a 
javascript issue.... cant remember details but its not unusual in the Ajax 
stuff to see...
... if(IE) do it all different...
... I think you working on the wrong side... its that Ajax, is my guess....

My guess is that it works with Firefox perfectly... but not on IE and you 
dont have a debugger for that... welcome to Javascript ;) on diff browsers 
its a nightmare ;)
Good luck, or maybe post the Ajax snippet and see if the guys can spot it...
