ICP parent

Perhaps I'm just confused. I've configured an ICP parent with the following

cache_peer netcache.insync.net parent 80 3130

Yet in my logs it seems that anytime there is a pause in activity of a few
seconds, the first URL received is fetched directly, and the parent is only
used for URLs that follow quickly before there is another pause.

So would this probably be a bug, a misconfiguration on my part, or a
"feature" so that the initial page can be loaded without waiting for ICP?
In my experiments, this is not specificic to .html URLs. If I go to a
directory index page with 100 small .txt files, if I go to each file very
quickly with only a second or two between them, they are all fetched through
the parent. If I pause halway through, for maybe 10 seconds, the next one
will be fetched direct.

On a completely unrelated note, I am seeing client side persistant
connections just fine, however 100% of my server side persistant connections
are only doing 1 request per connection (according to cachemgr.cgi stats).
Am I missing some config option here too?
