Use Persistent Connections (keep-alive)

[marvin-miller]

Hi Travis;

It's Windows 2000 / IIS 5.0 and keep-alives are enabled on the server and on the specific website.

Maybe I'm chasing a ghost (I don't really know what I'm doing) because this is what the requests look like which would seem (to me) to indicate that keep-alives are enabled?
