Help with URL Masking

iRule Newbie here and hopefully I am explain myself correctly. Our DevOps team requested I create a new site automate.test.mycompany.com, which will be redirected to this ansible URL/URI in our private cloud https://controller.automate.mycompany.com/#/login. In addition, they do no want the users to view controller.automate.mycompany.com/#/login in their browser.

virtual server: automate_https_vs
virtual server IP: 10.12.12.12 <----this IP is mapped in DNS to automate.test.mycompany.com
server pool name: automate_https_pool
server pool member IP and FQDN: 10.68.68.68 and controller.automate.mycompany.com <-HOST IS IN THE PRIVATE CLOUD

The VS and node are HTTPS; therefore, an HTTP profile and a client SSL profile has been configured.

Test performed:

1. When I perform an HTTP Request via the F5 VS to https://automate.test.mycompany.com, I receive an HTTP Response 404 error from the pool member/cloud host 10.68.68.68.
2. When I perform an HTTP Request directly to the cloud host by typing in the browser https://10.68.68.68  I also receive the same an HTTP Response 404 error.
3. When I perform an HTTP Request directly to the host URL https://controller.automate.mycompany.com I receive an HTTP response with the correct URL/URI path: https://controller.automate.mycompany.com/#/login.
4. Finally, I created a redirect iRule which redirects correctly, but I should not view https://controller.automate.mycompany.com/#/login when receiving the HTTP Response from the server. Since, the F5 is SSL bridging (encrypt/decrypt) the connection can we manipulate the HTTP response and change or rewrite the server side response? If so, I would appreciate your help.

when HTTP_REQUEST {  

switch [string tolower [HTTP::host]] {

automation.test.mycompany.com { HTTP::redirect "https://controller.automate.mycompany.com" }

}

}

Thanks,

Maria
