Setting up a PAC file to manage a proxy infrastructure
A work network can have complex traffic flows between local networks, connected vendor and partner networks, and the Internet. DNS domains are often split between internal and Internet hosts that require complex routing. A PAC file is an efficient way to manage a complex proxy infrastructure.
A PAC file is a
The benefits of using a PAC file:
- A PAC file allows you to automatically:
- Send Internet-bound HTTP, HTTPS, and FTP traffic directly to the proxy
- Send Intranet traffic directly to the destination
- Make exceptions for internal or external sites that must be routed or bypass the proxy
- A PAC file locks down theBlackBerry AccessLAN egress configuration
- A PAC file provides a flexible, easy-to-maintain, and script-driven method of controlling the routing of web requests
- A PAC file can include code that handles proxy load distribution and failover
- A PAC file can be stored and updated in a central location, instead of distributed on multiple servers and devices; when a PAC file is changed, client browsers retrieve the updated copy the next timeBlackBerry Accessis launched
- A PAC file can be configured to return DIRECT, NATIVE, BLOCK, or PROXY to have more granular control over browsing
- It is a best practice to keep the PAC file size under 1 MB to ensure proper performance.
- The return values in the PAC file must not contain spaces or newline characters.
- The PAC file must not be hosted on the same server asGood Controlor on the same server asBlackBerry UEMor any of its components. This configuration is not supported.
