Enable redirection to the original destination

Add the necessary Access rules to configure the redirection of unauthenticated HTTP or HTTPS connections from the status page to the destination that the user originally wanted to access.

Note: To redirect HTTPS traffic, you must enable TLS decryption for the traffic.

You must define the following IPv4 or IPv6 Access rules:

  • An Access rule that allows all clients to access destinations that do not require authentication.
  • An Access rule that allows authenticated users to establish HTTP or HTTPS connections.
  • An Access rule that redirects unauthenticated HTTP or HTTPS traffic to an Inspection rule.
  • An Access rule that refuses all HTTP or HTTPS traffic.

Using the HTTP_Request-with-redirect-capability Situation, you must also define the following Inspection Exceptions in the Inspection Policy:

  • An Exception that permits all matching connections to access destinations that do not require authentication.
  • An Exception that permits authenticated users to establish HTTP connections.
  • An Exception that redirects unauthenticated HTTP traffic to the logon page using the original destination URL as a parameter in the redirection.
