I'm using the simple account_location plugin to have virtual subdomains on my app (account.myapp.com - see Basecamp, Blinksale, etc.)
How do you go about setting up your OS X system to play nice? I'd like to use Apache & Mongrel.
Notes: The only thing I've able to accomplish is hardcoding the subdomains directly in my hosts file. I can get "test.localhost.com" to work fine, that's not really a wildcard subdomain. I wouldn't be able to test the app's ability to create and recognize subdomains
I'd gotten the tip to setup a local DNS server, but I couldn't get anything installed right.
