How to route Domain 1 and Domain 2 to the main site, so customers will see their content under their own domains?

[forward]

I am working on a project where multiple domain should point to a main site where a routing logic will display the right content based on the origin of the request.

How this can be achieved ?

Have a look at Cloudflare for SaaS Providers. This would allow you to direct other domains to your proxied server.
