I thought it odd as well, since I'm not having the problem with any other
site. Here's what seems to be unique about this site: among the reply headers
it sends out when handling a "Connection: Keep-Alive" request, it returns:
> > Connection: Keep-Alive^M
> > Keep-alive: timeout=10, max=999^M
Even though the server -says- it's providing 1.0 Keep-Alive compatibility and
even goes so far as to provide a timeout value, the server then tears down the
connection immediately. Upon doing some manual testing yesterday, I found that
most servers that do choose to honor keep-alive actually keep the connection
alive for the advertised period; this particular server, for some reason, tears
down the connection right away despite advertising a 10-second keep-alive. I
have my suspicions that this behavior is conflicting with iPlanet's
expectations of the response behavior, and also that squid (running without an
iPlanet parent) either compensates for this or somehow handles it more gently,
which is why others on the mailing list were unable to reproduce the problem.
