Some advanced options to allow CORS preflight requests bypass authentication, add X-Forwarded headers, etc.
X-Forwarded-For is a mechanism to finding out the source (IP and Port) of the connection. Pinggy HTTP(S) tunnel does not implicitly add the this flag. However, user can enable X-Forwarded-For header with x:xff command line argument.
