Passing 'sub-domain' through ELB to server

Context: I have multiple sub-domains under a domain example: abc.domain.com, xyz.domain.com, lmn.domain.com etc.

I have added a load balancer to my server and the server needs the sub-domain (in above eg: abc, xyz, lmn etc) to resolve to some functionality.

Issue: What should I use so that I can achieve this functionality?

Probable solutions: - Can I pass sub-domain name as a header from my application? - Can I append sub-domain as a "/path" to URL from my application and then ELB will work as per "host routing mechanism".

The (sub)domain name requested by the browser should already be there, in the HTTP Host header of each request.

Can I append sub-domain as a "/path" to URL from my application and then ELB will work as per "host routing mechanism".

No, you can't. Per-hostname routing uses the Host header to select a different target group, when you have multiple groups or instances or services configured with multiple target groups behind one Application Load Balancer. The path isn't modified by ALB.
