tcp probes

["Ramon Moreno" <rammor1@xxxxxxxxx>]

Greetings,

Can someone please explain to me how the tcp probes work in squid?

I get the following errors:

2008/08/22 19:43:09| TCP connection to 10.1.1.2 (10.1.1.2:80) failed
2008/08/22 19:43:09| Detected DEAD Parent: 10.1.1.2

Is squid actually requesting an image, or is it just trying to make a
socket connection to the port?

Thanks!
