In IE8 here on my XP SP2 system it works fine.
400 Bad Request is a server response which suggests that there is a problem
with the request headers. One major issue with IE, and this doesn't just
affect 8, is that the User-Agent string can get very long due to it listing
all the .NET versions installed on the PC. If you use a User-Agent editor
and strip out the .NET version numbers it might help here, as many firewalls
are blocking User-Agent strings that are too long.
In the address bar, type:
what does it show?
Now go to http://www.useragentstring.com/
, does it show the same string? If
not, then something running on your PC is corrupting the user-agent, and the
Audi site is throwing this error because it's checking the user-agent string
(many sites don't so you won't have problems). If they are the same, then it
could be that the Audi site is simply rejecting your request because it's
too long. Unfortunately the User Agent Utility from MS hasn't been updated
to work with IE8 yet, it just throws an error stating that the wrong version
of IE is installed. However, you can get registry scripts here:
and a handy utility here:
that will allow you to change it.
For instance, on my XP SP2 system my user agent could be stripped down to
Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; )
and it still identifies my browser as IE8.
It could be something else entirely though. Have you tried running in No
Add-ons mode? Start>Run and type
if that works, then you have an add-on installed for IE that is messing with
the requests sent to the Audi site (and likely many others too but has so
far not broken anything).
