title: List of browser as the are listed in IIS logs
body: <p>Greetings,</p>
  
  <p>I am looking for a list of browser entries as they are listed in an IIS log to help identify the different versions of browsers which visit our sites.  Perhaps there isn't a list but an algorithm which should be used to identify different browsers and their versions. </p>
  
  <p>Please note that I am not looking for a log analyzer, but the different values I can expect for browser version in a log.  If their isn't a list of these, is there an algorithm I can follow to determine what the browser is and it's version?</p>
