title: Reuse {{$randomInt}} in Postman
body: <p>My 1st request is: <code>GET http://example.com?int={{$randomInt}}</code>.
  I need to run 2nd request (with other tests in it) to the same address, so I need to save generated variable. How can I do it?</p>
  
  <p>I was trying <code>pm.variables.get("int")</code> in the "Tests" sandbox after 1st request, but this code cannot see <code>int</code> var.</p>
  
  <p>Creating random number in Pre-req. sandbox to 1st request:
  <code>postman.setGlobalVariable('int', Math.floor(Math.random() * 1000));</code> 
  doesn't help either, because I need to use this param in the URL, while "Pre-req." block is run after request but before tests.</p>
  
  <p>So how can I generate random var before 1st request and store it to use in 2nd request?</p>
