>From the time stamps in your trace, how long is the request taking for
both browsers (what time elapses from the first packet to the last)? The
embedded portal has a pretty short "alarm" put on the process to help
prevent possible DoS attacks. Perhaps it is a bit too short. It could
also have something to do with that extra newline you speak of... the
script will read the content (based on Content-Length) and if there is
extra then it could be timing out on the read (and thereafter failing
because of the SIGALRM).
