On Oracle iPlanet Web Server 6.1.x, if the HeaderBufferSize is set in magnus.conf to a value greater than 32768, then the error response "HTTP/1.1 400 Bad Request' is sent to the second request in a keepalive session.

4] This returns the HTML response and keeps the telnet session in keepalive mode. Issue the same GET request.
5] The 400 response is returned.
