title: Want to use both GET and POST methods
body: <p>I know result page that uses GET method can be bookmarked while the one using POST cannot be. I also know about the restrictions of the GET methods. </p>
  
  <p>Now suppose I want to build a search engine which by default uses GET allowing users to bookmark but when the length of the search phrase exceeds the limit, switch to POST. On the server side I make use of $_GET or $_POST depending on which is set.</p>
  
  <p>Is this doable?<br> 
  If no, why?<br>
  If yes, please provide a brief outline.</p>
  
  <p>Thanks</p>
