A route is an address at which applications can be accessed from. The two main types of routes are HTTP routes, which are those created in HTTP domains, and TCP routes, which are those created in TCP domains.  

The difference here, aside from the domain types, is that HTTP routes communicate on port 80 and 443 and cannot reserve any other ports. In contrast to TCP routes, which do not support hostname and paths and has a single use port, that, once reserved, cannot be used again for another different route. A key aspect of HTTP routes in Cloud Foundry is that incoming requests will reach the GoRouter, after a load balancer, that maps specific HTTP routes to applications.
