Symptoms

Performance impact after enabling HTTP/HTTPS Proxy

Cause

Enabling the HTTP/HTTPS proxy functionality can impact a performance in situations where proxied traffic would otherwise be accelerated by SecureXL.

In order to proxy the connection, the FireWall creates 2 separate connections:

one from the client to the proxy
and another between the proxy and the destination

Because of this, SecureXL cannot accelerate these packets.

It is further relevant to note that the HTTP/HTTPS proxy is NOT a caching proxy. It does not cache commonly visited web pages to provide faster local access to hosts on the LAN.
