Re: [squid-users] Why no graphics?

Sing along:

Henrik is the greatest
Henrik knows it all
There isn't a Squid problem in the ocean
That Henrik could not call.

Ok, ok, just a quick hymn :-)

But back to business: turning off server persistent connections made no
difference but turning off client persistent connections made all the
difference in the world, for both IE 5.5 and Netscape 6.2 I might add.

It seemed that with the default settings Netscape was faster but individual
pictures still only popped up every 10 seconds or so.

Is there any penalty to disabling persistent connections, other than the
reconnects from the browser to Squid?

Cheers,
Caro
