1523	large_client_header_buffers directive is ignored in server context	Andrey Kartashov		"`large_client_header_buffers` works in **http** context, but ignored in **server** context, despite the fact it is allowed there.

To reproduce on clean installation:

Add into configuration:

{{{
  server {
    listen 80;
    server_name b;
    large_client_header_buffers 4 64k;
  }
}}}

Make sure hostname ""b"" resolves to your IP (via hosts file, f.e.)

Try curl with URL bigger then default buffer size (8k), f.e.:

{{{
curl -I http://b?`perl -e ""print 'A' x 10000;""`
}}}

Expected reply:

  HTTP/1.1 200 OK

Actual reply
