title: URL query string has a comma in the string
body: <p>I am having an issue with a URL query string and I believe the issue is that my parameter sometimes has a comma in it.</p>
  
  <p>What happens is I have a query string that is generated from a list of group names so that my string looks something like:</p>
  
  <pre><code> Group=GroupName1,GroupName2,GroupName3
  </code></pre>
  
  <p>While doing some testing I noticed that some of my groups are not being displayed on the page even though they are in the query string. Then I noticed that the groups that are not showing are those that have a comma in the name. For example:</p>
  
  <pre><code> Group=People,%20Places%20and%20Stuff
  </code></pre>
  
  <p>Obviously the query string gets parsed looking for 'People' as a group and 'Places and Stuff' as a group. This is an issue because the group is 'People, Places and Stuff'. I don't have any control over the group names so they cannot be changed to not include commas. I tried to encode the comma in the string using %2C however that had no impact.</p>
  
  <p>I did some searching but I couldn't find anything other than a suggestion about changing the server so that the delimiter isn't a comma but I don't have the ability to that. Any other solution or am I stuck?</p>
