The portal https-redirect blacklist command adds an address to the HTTPS redirection blacklist. After an address is added to the HTTPS redirection blacklist, HTTPS redirection is not performed for HTTPS access to this address of Portal users.
The undo portal https-redirect blacklist command removes an address from the HTTPS redirection blacklist.
By default, no address is added to the HTTPS redirection blacklist.

Usage Scenario
Before users pass Portal authentication, HTTPS access to a website other than the Portal server triggers HTTPS redirection by default. To disable HTTPS redirection for HTTPS access to a specified address, run the portal https-redirect blacklist command to add this address to the HTTPS redirection blacklist.
Precautions
If an address has been added to the HTTPS redirection whitelist using the portal https-redirect whitelist command, this address cannot be added to the HTTPS redirection blacklist.
If an address (except the address of the Portal server) is not in the HTTPS redirection blacklist, HTTPS access to this address will always trigger HTTPS redirection before users pass Portal authentication.
