I've googled like crazy but can't find an answer to this.
How do I change the page displayed for http://www.mydomain.com/? (Right after the web app is created the page defaults to index.html. I'd like to change this!)
You can't change it.
Lift converts the request for "/" to List("index"). Any "blank" part of the request path is converted into "index". Thus, the "index.html" template will be used to serve "/index" and "/".
