I received this which details more about the error - hopefully this helps.
I have been looking at the traffic sent /received by the different browsers and there is definitely something different. The part of the error messages I sent you that looked interesting to me was the missing variables sesskey and related. When I sniff the traffic from firefox I can see values are being passed like this:
'sesskey' : 'X0tK2ydq86GFeD31',\n
However in internet explorer I see the following:
'sesskey' : '',\n
Which obviously causes the error I mentioned in the previous email.
When I work backwards from here I can see internet explorer is doing something different with the negotiation
Vs firefox which works fine
I see also on the line a couple previous: Proxy-Authorization
IE Proxy-Authorization: Negotiate TlRMTVNTUAABAAAAl4II4gAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==\r\n
Firefox [truncated] Proxy-Authorization: Negotiate TlRMTVNTUAADAAAAGAAYAHwAAABsAWwBlAAAAAgACABYAAAABgAGAGAAAAAWABYAZgAAABAAEAAAAgAAFYKI4gYBsR0AAAAP/ZhgsHJQtT0KV6EYzqDS6VMAVABBAEMAQgBSAFUASQBDAFQARQBOAEcAUwAtAEIAUgBVAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
So the IE version looks to have lost a big chunk of the key which might cause the failure of the negotiation and disrupt the passing of the missing values?
And the line up one again relating to the cookie
IE [truncated] Cookie: __utma=61070256.1103620605.1331598478.1335130693.1335134134.19; __utmz=61070256.1332300789.9.2.utmcsr=webhelpdesk:8081|utmccn=(referral)|utmcmd=referral|utmcct=/helpdesk/WebObjects/Helpdesk.woa/wo/SILu1GSSYVwZq5Kdj6QQOg

I have cleared the cookies in IE but doesn’t make a difference, I suspect the line with the proxy-authorization is the problem though I don’t know why this would happen.
