Hi.
I'm learning to use squid.I have this problem: I have to configure squid to
cache a webserver running on a machine with ip 192.168.11.224:8180. squid runs
on another machine with ip 192.168.11.233. my config file is:

http_port 80
http_port 8180

As You can see i have problems in caching psml pages and other.
My question is : is my conf file "completely" wrong to store the whole dynamic
and static contents of my webserver? and, is it posiible to use cached object
even if webserver is down temporarily?
Sorry if i missed something but i'm relly newbie. Thank you anyway, Matteo
