web-proxy

I can see there is a feature supporting subdomains with cristianoliveira/ergo#11 and I'd like to ask if it would be possible to add wildcard subdomain support, something like the following format:

*.mydomain http://localhost:8080

will resolve to every subdomain automatically, like:

test.mydomain.dev
user10.mydomain.dev
admin.mydomain.dev

To works with the https://uportal-project.github.io/WebproxyPortlet the docs/README.md entry point is missing.
This part need some updates.
