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 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 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.
