Duplicate Referrer Header - HTTP.sys barfs - Stack Overflow

[Julian Reschke]

See
<http://stackoverflow.com/questions/1715138/duplicate-referrer-header-http-sys-barfs>:

it appears IIS has started rejecting request with duplicate Referer
headers; does anybody know whether this applies to similar kinds of
broken requests?

My first question would be whether this has been confirmed on a different
IIS installation? Or if it is a new issue or just discovered because of
the particular application situation?

I've seen it with duplicate Host headers (which makes more sense, at  
least).

Using Mark's tool...:

<http://redbot.org/?uri=http%3A%2F%2Fmsdn.microsoft.com%2Fxyz&req_hdr=Referer%3A%2Fx&req_hdr=Referer%3A%2Fy>

So it appears IIS 7.0 does this already.
