title: Alternative to sending comma separated parameter by querystring
body: <p>I am trying to send querystring parameter as below but i think that using comma in querystring is not valid so what is better alternative to comma separator for path parameter?</p>
  
  <pre><code>&lt;a href="/?path=1,2,3"&gt;&lt;/a&gt;
  </code></pre>
  
  <p>I don't want to send like <code>&lt;a href="/?path=1&amp;path=2&amp;path=3"&gt;&lt;/a&gt;</code> which can be quite long.</p>
