Use a proxy auto-configuration (PAC) file to selectively drive HTTP traffic through either the inline bridge or the HTTP/S proxy path of the Symantec Web Gateway.
When you configure Internet Explorer to use a PAC file, it caches the proxy server information for each host on a host-by-host basis regardless of whether you use HTTP or HTTPS. The result is that some Web sites may be temporarily inaccessible when you switch between HTTP and HTTPS.
To resolve this issue, disable automatic proxy caching in the registry file or group policy settings.
