title: different domains pointing to the same rails app
body: <p>I'm creating a rails app where users will be able to create and manage multiple blogs from their accounts. The app will be hosted on www.mydomain.com but i want users to specify a domain they own and be able to point it to any of the blogs they've created so that they can have www.usersite.com point to www.mydomain.com/user/:user_id/blog/:blog_id</p>
  
  <p>that way it looks like is being hosted on their site even though is not</p>
  
  <p>i've been reading some post and maybe CNAME is the way to go for this, but i'm pretty new to creating rails apps and if anyone can help me or point me in the right direction i would appriciate it.</p>
  
  <p>If you need me to clarify anything please let me know</p>
  
  <p>Thanks in advace
