Using ngrok with Virtual hosts (MAMP, WAMP, etc)

Popular web servers such as MAMP and WAMP rely on a technique popularly referred to as 'Virtual Hosting' which means that they consult the HTTP request's Host header to determine which of their multiple sites they should serve. To expose a site like this it is possible to ask ngrok to rewrite the Host header of all tunneled requests to match what your web server expects. You can do this by using the --host-header option (see: Rewriting the Host header) to pick which virtual host you want to target. For example, to route to your local site, you would run:

ngrok http 80

You can also use rewrite to tell ngrok to use the local address hostname.

ngrok http --host-header=rewrite 80
