[squid-users] Any obvious security issues in my squid.conf?

[j m]

I will be remotely accessing squid 3.5 for general web usage, using an encrypted browser-to-proxy connection, and username/password authentication.  I believe my config is reasonably secure as it's based off the default config, but I'm unsure of myself due to some confusion.  Are there any glaring issues with what I have?
