The "Connection: Keep-Alive" header is terminated with just "\n" (hex 0A)
instead of "\r\n" (hex 0D 0A), like every other header. According to
HTTP/1.1 spec, request/response headers MUST be terminated by "\r\n".

So, the client is truly sending a "bad request".

Assuming I read this right, it may be you haven't enabled parent paths
on IIS6.

hello david

thank you very much for this answer! i already read about this "lf
/cr&lf"-thing, but this time i didn't see the wood for the trees Wink
unfortunately i cannot change the client-behaviour by myself (but i
alreadysent a message to the support of the company developing the client.)

do you know if the patched http.sys (Microsoft Knowledge Base Article -
828726) would be helpfull here?

IIS5 was not so "sensitive" about this type of "bad request" Wink

just wondering: how about HTTP/1.0 - need for "\r\n" (hex 0D 0A) too?
because, as you see, the client does a HTTP/1.0-request (GET / HTTP/1.0)

kind regards,
curtis

No, 828726 would not help here. That article indicates how many broken HTTP
clients there are out there -- the HTTP spec specifically states that HTTP
Verbs are case sensitive and are all upper case, but dumb client
implementations chose lower case...

In short, there's many broken clients out there which don't follow spec, and
over time, these things will happen. And, as there tends to be thousands of
such clients per instance of the server, people tend to want server-side
"fixes" for these client-side problems -- quite the nightmare that HTTP
designers feared, due to people not following spec. Strangely, people
complain about IIS does not support the HTTP spec, yet these same people
complain when IIS enforces the HTTP spec. Seems that people just want to do
whatever they want, damn the spec -- which isn't that smart from an
interoperability perspective at all -- but strangely, they scream when
Microsoft supports something outside the spec. Go figure -- a lose-lose
demand.

BTW, HTTP version does not change the definition of headers delimiters.

IIS5 was not so "sensitive" about MANY bad things, including Code Red. It
doesn't mean it's "correct".
