title: Regex to check IE version
body: <p>I need to block IE versions upto 6. for user agent strings I wrote a regex which blocks IE 4 5 and 6. But I came across this string: </p>
  
  <p><code>Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; TheFreeDictionary.com; FunWebProducts; FBSMTWB; GTB6; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; InfoPath.2)</code></p>
  
  <p>In this string, there is MISE 6.0 mentioned so my regex blocks it. However it is actually IE 8 browser. So how can I construct a regex that scans for IE which is above 6 and if IE 4-5-6 appears again in the string it will ignore it.</p>
