title: How to create a mirror website?
body: <p>I would like to know how can we set up a mirror web site of a main web site ?
  EG: Imagine that my domain is www.somedomain.com, someone is accessing to this domain. but that time the server is down/had some problems this time I need to redirect the user to another server. which have the same copy of main website. is it possible to redirect like this 
  ? I searched some forums i found that adding name server will redirect to mirror site but some people are saying this is not a good way to do this. can anyone tell me how can i do this?</p>
  
  <p>Thanks and regards.</p>
