title: How to set uid for every sever request?
body: <p>I work in web analytics. We are using both <a href="http://en.wikipedia.org/wiki/Server_log" rel="nofollow">server logs</a> and client side data (collecting user interaction information using javascript plugin) to get more accurate data, For finding repeat visitors we are using <code>uid</code> </p>
  
  <p>Client side we are generating the <code>uid</code> and set in the cookie as same as <a href="https://developers.google.com/analytics/devguides/collection/gajs/" rel="nofollow">Google Analytics</a>. We must store the <code>uid</code> in the server logs so that we can track the user both ways (using server logs and client side data) and merge the data for better analysis.</p>
  
  <p>How do I send the <code>uid</code> which is generated in the client side to the server to save the <code>uid</code> in the server logs?</p>
