title: .net Unconsistency in Request Browser version
body: <p>i had created an empty c# web site with just one page with Request.Browser.Version &amp; UserAgent output on it. Then hit it with different Chrome versions using "User-Agent Switcher" Chrome extension. </p>
  
  <p>For time to time, though the Request.UserAgent is correct, Request.Browser.Version seems to return wrong value:</p>
  
  <p>"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.16 Safari/537.36" Returned Request.Browser.Version:39</p>
