title: Keeping the same url parameters when user browse to other pages on the site
body: <p>I'm interested in keeping the same url parameters the user already have, when he browses to other pages in my website.</p>
  
  <p>For example if he enters through the link
  <code>mysite.com/?phone=9384839484</code>, then any internal link on the site should redirect him to <code>mysite.com/internalpage?phone=9384839484</code></p>
  
  <p>The purpose is to track phone calls from each platform by showing them the same phone number everywhere on the site.</p>
