lws minimal http server multivhost

This creates a single server that creates three vhosts listening on both :7681 and :7682. Two separate vhosts share listening on :7682.

vhost listens on port serves
localhost1 7681 ./mount-origin-localhost1
localhost2 7682 ./mount-origin-localhost2
localhost3 7682 ./mount-origin-localhost3

Notice the last two both listen on 7682. If you visit http://localhost:7682, by default you will get mapped to the first one, localhost2.

However if you edit /etc/hosts on your machine and add

127.0.0.1 localhost3

so that you can visit http://localhost3:7682 in your browser, lws will use the Host: localhost3 header sent by your browser to select the localhost3 vhost for the connection, and you will be served content from ./mount-origin-localhost3
