Trying out LaunchRock, and ran across this:

general-instructions-for-creating-your-cname-record

Basically as far as I'm able to tell they only support using your sub-domain as the URL, not having the "launch page" at "subdomain-by-you.launchrock.com".

Guessing the guide to changing the subdomain and CNAME means you create a subdomain and then while the user sees "signup.yoursite.com" the DNS call is really going to LaunchRocks servers and being routed to the custom page you set up with them, though that's just a guess on my part.

Host Name/Alias: Enter the part of the address that you picked in the
LaunchRock control panel. For example, if you picked
signup.yoursite.com as your address, enter signup.

Value/Destination: Enter sites.launchrock.com.


From user's POV it means:


While this CNAME for you host (site) is active, any visitor of signup.yoursite.com will see "some page" from launchrock.com server (with personalization for site?)


From backend:


DNS resolve signup.yoursite.com to IP of sites.launchrock.com.
Browser send request for HOST: signup.yoursite.com to host sites.launchrock.com
Processing rules handle incoming request and map it to some local resource (page, logical path launchrock.com/signup.yoursite.com/ ???), which http-server returns back to browser
