// Package main an example on how to catch dynamic subdomains - wildcard.
// On the first example (subdomains_1) we saw how to create routes for static subdomains, subdomains you know that you will have.
// Here we will see an example how to catch unknown subdomains, dynamic subdomains, like username.mydomain.com:8080.

admin.mydomain.com, and for other the Party(*.) but this is not this example's purpose
