title: Direct users to web page, based upon their city
body: <p>Hii, </p>
  
  <p>We want to redirect our users to one of our web pages corresponding to the users city (location based upon the users ip address and using some ip location databases)</p>
  
  <p>My question is, how to make it work fast? for example in website gropoun, whenever the user visits, it instantly takes the user to its city page.</p>
  
  <p>Thanks.</p>
  
  <p>Edit: We are using PHP</p>
