How do I prevent Squid from caching SABnzbd?

[Grandpuma]

I know there is a Do Not Cache setting that I can enter a domain address but would I enter my providers web address there or the localhost:port in that box or is there some other way. I can't see the need for my pfsense hard drive to work full time caching something that I am downloading.

I assume there is an easy way but I am not sure how to or what to block.

Thanks!

I may be wrong but I'm pretty sure Squid would only cache traffic that flows through it. I connect to my news reader on port 563 (or whatever it is) so squid would never seem my newsreader traffic as squid only has traffic from port 80 flowing through it!
