title: Can you suggest good ways of generating URLS for viewing tagged content
body: <p>For example, here on stack overflow the URL <a href="https://stackoverflow.com/questions/tagged/javascript+php">https://stackoverflow.com/questions/tagged/javascript+php</a> will give you all questions tagged with javascript and php.</p>
  
  <p>The system I have allows tags with spaces in them, so the approach used here would not be a good fit for me.</p>
  
  <p>What character would you use to separate the tags, so the URLs are still human readable, google readable and web browser compatible.</p>
  
  <p>My gut feeling was to use commas. eg <a href="http://example.com/tagged/first+tag,second+tag" rel="nofollow noreferrer">http://example.com/tagged/first+tag,second+tag</a></p>
  
  <p>Any feedback or suggestions would be welcome.</p>
