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

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?

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.
