Attempting to access a web site through the Symantec Web Gateway setup in Proxy mode may take up to 5 minutes to load the page, but when you by-pass the proxy the page loads immediately.
When analyzing a packet capture taken of the connection attempt to the problem web site it was found that the Symantec Web Gateway is making standard connection request but the server sends the response back 6 bytes at a time over several minutes. This is an issue in how the distant web server is responding to an SSL/TLS connection request, and not an issue with the Symantec Web Gateway.
The solution for this issue is to have the client web browser(s) by-pass the Symantec Web Gateway Proxy via PAC file or GPO when accessing that particular web site.
