    Hi,

     

    I think, application is redirecting it to http again. Can you please confirm below points ?

     

    1. Do you have F5 VS running on port 80 with same IP which is used for https VS?
    2. And you have mapped same pool/irule to above VS.

     

    If above points are true in your case, you should remove pool/irule from port 80 VS and add F5 provided http-to-https iRule to it. So F5 will again redirect that request to https.

 ,

 

As you are using Client-SSL profile on the Virtual Server but no Server-SSL profile, it means the session between Client and F5 is always encrypted whereas session between F5 and backend server is plain text/unencrypted. So in any case, to & fro traffic between client and F5 will be encrypted.

    Hi Mayur

    but the client is receiving response in http instead of https.

    is this the way that it should be working or is there anything missing on the F5 config?
