I've also seen this issue when a "Accept-Language" locale header is missing from the request - and for some reason SpringMVC (which Surf is now part of…) gets very upset if it is missing (you get the same problem from curl - so need to set the same header there also). I wonder if some requests from IE are missing it when running in https (wouldn't be the first IE https bug that's for sure!!). Are you using 3.4? I'm wondering because the MTAuthenticationFilter filter has new code in it to fix this issue and force the setting of an "Accept-Language" header to a value of "en_US" if nothing is set.

Thanks,

Kev

From what I can see in the code, this has been fixed for 3.4.b! The second 3.4 community release is due out today. So look out for posts/download locations shortly.
