Hello Victor,

A HTTPS-to-HTTPS redirection like this will require you to do the SSL offloading on the load balancer, in your case you have a CSM so you also need a SSL module that can take care of the traffic decryption.

If you don't have a SSLM then your option would be to configure a HTTP redirect on the server itself.

Hello Pablo.

Thanks for your answer, the ssl is ended in the servers, so theres no way to do that? unless i terminate the ssl in the CSM?

Regards

Hello Victor,

That's right, when balancing HTTPS the load balancer is able to check the packets up to layer 4; all the information contained in the HTTP header such as URL is encrypted.

When you happen to have a SSLM the CSM will accept the traffic on HTTPS, send it to the SSLM for decryption once decrypted it will return to the CSM to take a peek to layer 5 and from there do either the HTTP redirection or forward for load balancing.

In your case since the servers are taking care of the decryption of the traffic you can have them configured to the HTTP redirection to the new domain.
