Is CNAME really a redirect method ?

Hello kridsana,

As evoqued Stanislas The dns part is independent of the requested part.

To make it simple, when you enter "a.example.com" in your browser, the DNS resolution is done by the system. but in no case a redirection is done by dns or browser.So CNAME can't redirect URL which we input to another URL...

If your service is hosted by F5, you can set a rule to allow you to redirect your request to another host.

but if this is not the case you have to find you have to find other solutions. I do not think that's the best solution, but you can for example hosted a service in F5 for host "a.example.com" and juste implement a redirection on host "b.login.aws.com". the other solutions is to see the side of your host so that he can make the configuration necessary to accpter the host "a.example.com".

But I'm not sure that in this case, GTM can help you because all it will do is return an IP and never redirect you...

let me now if I can help you.

Regards
