With the HTTPS Proxy is enabled, Decryption Policies handle all HTTPS policy decisions. You can no 
longer define Access and Routing Policy group membership by HTTPS, nor can you configure Access 
Policies to block HTTPS transactions. 

If some Access and Routing Policy group memberships are defined by HTTPS and if some Access 
Policies block HTTPS, then when you enable the HTTPS Proxy, those Access and Routing Policy groups 
become disabled. You can choose to enable the policies at any time, but all HTTPS related configurations 
are removed.

format types, such as Visio files and some third party applications.
