Hi Simon,

I think we're not talking about the "same IWA".I mean IWA as described
for example here [1] or here [2].

If that's what you're actually doing, would you be so kind to post (or send
me off list) a dump of the request/response headers of the Windows 7
successfully doing IWA (going through Squid, obviously)?

Thanks, Javier
