Is it possible to bypass a proxy when the proxy settings are set to Auto Proxy Config

dnsPROXYrails

I've set up Automatic Proxy Configuration (PAC) in OSX Snow Leopard to point to a URL. I've also filled out the "Bypass proxy settings for these Hosts & Domains" box because I want to skip the proxy for certain sites. (I'm using pow which as far as I understand, works by creating a local mini dns server.)

If I use Apple's Web Proxy/Secure Web Proxy, it'll use my settings for bypassing the proxy, but apparently not for PAC. Any way to make this work?

Best Answer

Just ran into this as well and it doesn't seem to apply the "bypass" sites when using the auto proxy settings. I suppose that is the intended behavior, otherwise it wouldn't be very "automatic".

I just entered the proxy settings manually and it worked for me.

The mac firewall must be disabled for this to work.

It turns out the solution was to bounce mDNSResponder:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

This was obtained by a different coworker from this Server Fault question.

OS X 10.10.0 – 10.10.3, Yosemite

Apparently, mDNSResponder doesn't exist in Yosemite (OS X 10.10). You can restart descoveryd instead to fix these issues.

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

OS X 10.10.4+, Yosemite

In OSX 10.10.4 the mDNSResponder has been reintroduced. So use the first one will work again.
