Disable ssl or https for the embed url

Hi Ztan,

Since the webpage is running SSL, disabling SSL or redirecting to http will not work.

The problem may be caused by SSL SNI. When I send request to cdn.fusioncharts website without SNI extension in Client hello package, I get reset packet. 

I am not sure if there is a configuration for SNI in the Secure Web Gateway configuration. The following article says the following: For SSL-encrypted traffic, select Use SNI in Client Hello (if SNI is not available, use Subject.CN) or Use Subject.CN in Server Cert.
