Description

HTTP Strict Transport Security (HSTS) is a security enhancement that is specified by a web application through the use of a special response header. Once a supported browser receives this header, the browser will prevent any communications from being sent over HTTP to the specified domain and will instead send all communications over HTTPS. It also prevents HTTPS click through prompts on browsers.

This KB article describes how to enable this option using a Configuration Extension Mechanism (CEM) of the AMC.

Note:

HTTP Strict Transport Security (HSTS) is support from 11.4.0 onwards
HTTP Strict Transport Security (HSTS) is disabled by default
Once HSTS is enabled, users cannot override certificate errors or warnings if a self-signed certificate is used for the portal or if there is a host name mismatch.
