I now checked that, the request doesn't appear in the server's log.

It didn't. Even downgrading to curl7.11 didn't help.

But last night i remembered that we are running a transpartent Proxy somewhere on the firewall and I'm now quite sure the problem lies there somehow.

I just now found out that our transparent proxy seems to get confused with curl's user agent header.

A request

curl -A curl http://curl.haxx.se/

get's through, a request

curl http://curl.haxx.se/

doesn't.

So I've got to talk to our network people. But just so I know: is your User Agent Header:
User-Agent: curl/7.12.3 (i386-pc-linux-gnu) libcurl/7.12.3 OpenSSL/0.9.7e zlib/1.2.2 libidn/0.5.2

RFC conform? (just in case they tell me: "Fix curl, we do the right thing).

Bye
Tim
