Remove jQuery timestamp from json requests to hit Drupal cache

Mon, 02/22/2016 - 10:33
Problem: When ajax request has cache off it always creates request with timestamp e.g. `_=1456134256000`, and as it is get parameter, views are called and Drupal cache is not hit. And when cache is on, request is made without timestamp, and browser returns data from it's cache, so it doesn't hit server. What I needed is that script gets past browser cache, but hits Drupal cache.
