title: Pointing domain to a page in my site
body: <p>I'm having a directory website with sub-pages for each city. Like for example
  Newyork will have an address www.directory.com/newyork, LA will have www.directory.com/la</p>
  
  <p>so i want to point the the domain newyorkdirectory.com to  www.directory.com/newyork
  and so for each sub sections... what are the options I have.. can I do this in my code? Is there any way to detect the domain from php and load the content accordingly?</p>
  
  <p>If all i point all the domain's to the site can i detect the incoming domain and refer them to a page? I totally have no idea on this.</p>
  
  <p>Clarification:
  when people goto the site through newyorkdirectory.com the page 
  www.directory.com/newyork/malls should be accessed through newyorkdirectory.com/malls</p>
