title: redirect user, then log his visit using php and mysql
body: <p>I have a PHP redirect page to track clicks on links. Basically it does:</p>
  
  <pre><code> - get url from $_GET
   - connect to database
   - create row for url, or update with 1 hit if it exists
   - redirect browser to url using Location: header
  </code></pre>
  
  <p>I was wondering if it's possible to send the redirect to the client first, so it can get on with it's job, and then log the click. Would simply switching things around work?</p>
