title: LogParser and multiple query string arguments with the same name
body: <p>I'm trying to get IIS logs statistics with LogParser, and I have to group numbers by the values that a certain argument, named 't', can assume on the query string. We have to handle scenarios like this one:</p>
  
  <pre><code>.../?t=act&amp;t=fcst&amp;t=be
  </code></pre>
  
  <p>where the same argument is specified more that once, and when I do the count I would like to have such an url to count 1 for each value that t assumes on the query string. Using:</p>
  
  <pre><code>EXTRACT_VALUE(cs-uri-query,'t')
  </code></pre>
  
  <p>only the first occurrence of t (=act) is processed, so my counts does not get increased for values fcst and be.</p>
  
  <p>Is there a way to handle such a case without further post-processing?</p>
