title: How to get list of network requests done from javascript?
body: <p>I am loading new web page in new tab from my javascript by writing below code. <code>window.open('www.gmail.com','_blank')</code>
  While the new tab is loading I would like to read all redirected url's in the network tab(chrome devtools). I tried to reload all url's using <code>performance.getEntriesByType("resource");</code> but here the issue is my existing application is refreshing.
  To make this question more clear.
  1) I have my existing application lets a gmail only.
  2) When I click on one button(lets say compose in gmail ), it has to open new web page in different tab.
  3) When the new page gets loaded completely I would like to read all loaded urls' in the network tab in chrome dev tools.
  4) While  reading those url's from chrome network tab my existing page  should not refresh. </p>
