title: Store variable using sessions
body: <p>I have a variable which is updated on every page shift, but I want to store the value in the first call for good somehow. </p>
  
  <p>The variable is e.g</p>
  
  <pre><code>   $sizeOfSearch = $value['HotelList']['@activePropertyCount'];
  </code></pre>
  
  <p>First time the page loads it's 933, on next page the same value is retrieved but it's now different e.g 845. This goes on page for page. </p>
  
  <p>What I want is to store 933 for good. So I can show this number on every page.</p>
  
  <p>Can I somehow store the first time this value is retrieved ? (I get the value via REST request)</p>
  
  <p>Sessions maybe or ?</p>
