The HTTP Proxy feature is available with SmartServer 4.0 and higher.

While the SmartServer provides the necessary security for most applications, you can configure SmartServer HTTP proxy settings to further enhance security. With HTTP proxy, security personnel can shut down traffic to a device that may have been compromised. 

You can configure HTTP proxy to use either a locally hosted HTTP proxy, or an external HTTP proxy so that all HTTP and HTTPS traffic is routed through a configurable proxy to ensure network security. As all of the HTTP traffic (from the SmartServer to the HTTP proxy, and from the HTTP proxy to the end destination) is redirected to go through one particular proxy, a root certificate that the proxy uses to consider it trusted can be uploaded using the SmartServer System Configuration page. A certificate file and credentials (for authentication) can be provided, but are not  required.

This section consists of the following:
