Re: ICP parent

I just upgraded to patch2, took the default squid.conf, and added only one
line:

cache_peer netcache.insync.net parent 80 3130

Then I go to any site:

908280672.194 3673 209.16.31.13 TCP_MISS/200 953 GET
http://www.digex.net/ - DIRECT/www.digex.net text/html

http://data.digex.net/images/h-about.gif -
FIRST_PARENT_MISS/netcache.insync.net image/gif

And as always, the first object retreived after any pause in activity is
fetched directly instead of through the parent. Any ideas? Shouldn't every
URL be fetched from the parent except those I have in the stoplist?
("cgi-bin" and "?" URLs)

It doesn't only happen to html files. If I go into a directory listing of
20 text files, and pick one, it comes direct. If I very quickly back up and
hit the next file it comes through the parent. If I then pause 5 or 10
seconds, and hit another link, it comes direct. It seems to just be that
any object fetched after an idle pause is fetched directly. Any ideas?

Also, after the upgrade and default configuration file, I'm still not seeing
any server side persistant connections. Is there something special I need
to do to enable them that is not on by default in the conf file?

Server-side persistent connection counts:

 req/
 conn count
 ---- ---------
    1 140
