The no_cache directive just prevents Squid from caching received data from a site. The negative_ttl directive controls "Time-to-Live (TTL) for failed requests".

I would have to imagine that SquidGuard is doing the blocking in this case, as I don't see any problems with your Squid ACLs. For what it's worth...

...is redundant. The local_net and our_networks are two ways of declaring the same subnet.

Try removing SquidGuard as a cache_peer, restart Squid and see if access to www.mysite.com works. That will at least narrow the cause of the problem.
