HTTP/HTTPS Redirection with DP Offload

This feature improves handling of HTTP/HTTPS redirection requests that occur when user authentication is required for users to get access through the security appliance. HTTP/HTTPS requests received from sources that are not authenticated users are redirected to the security appliance’s login page, which is served up by its built-in web server. This redirection happens if Single Sign-On (SSO) cannot identify the user or if SSO is not in use.

This feature improves efficiencies in both the web server and the HTTP/HTTPS redirection processes, and offloads most of the redirection processes to the Data Plane (DP) where the processing can be spread across multiple cores.

Elements of this feature can be controlled by internal User Authentication Settings options. This includes an option to globally enable/disable redirection processing in the DP, a flush option to clear the redirect files cache, and an option to specify the internal NAT port number used for the web server.
