title: Is there an infallible method to redirect depending on browser and browser version?
body: <p>I would like to redirect users to another webpage depending on the browser and browser version he/she is using.</p>
  
  <p>I know this can be done with simple javascript code and also with PHP with the <code>HTTP_USER_AGENT</code> parameter. However, both methods can be evaded either deactivating javascript or changing the user_agent manually.</p>
  
  <p>My question is: Is there  way to redirect that gives no chances to the client to evade it?</p>
