Requests are connecting directly instead of being redirected to the ProxySG appliance

Products

• ProxySG Software - SGOS

Issue/Introduction

User requests are connecting directly to the origin content server (OCS) instead of the ProxySG appliance, even though you have specified in the Proxy Auto-Configuration (PAC) file that these requests should be sent to the appliance. You can verify that requests are connecting directly by using a network monitoring utility such as TCPView.exe to determine where the browser is redirecting. 

Environment

Explicit proxy deployment

Resolution

This problem has more than one possible solution:

• If the PAC file specifies that requests go direct if the ProxySG appliance cannot be reached, verify that the appliance in question is reachable.
• Debug the JavaScript in the PAC file. Look for incorrect syntax and other errors.
