Alternate PAC file addresses

Alternate PAC file URLs are in the following format:

http://pac.webdefence.global.blackspider.com/proxy.pac

https://pac.webdefence.global.blackspider.com:443/proxy.pac

Alternate PAC file URLs use the standard ports for web browsing: port 80 for HTTP traffic, and port 443 for HTTPS. This is useful for users who connect from locations (such as guest or public networks) where non-standard ports may be locked down.

For locations where ports 8081 and 8082/8087 are locked down, use the alternate PAC file address to ensure that users can retrieve the PAC file and browse via the cloud service.
