title: Angular RxJS - How to monitor progress of HTTP Get Request (not file)
body: <p>How to utilize Angular HTTPClient's <code>progress</code> event to show progress in percentage of Get request which does not necessarily a file request?</p>
  
  <p>Currently HTTPClient's <code>progress</code> event fires after request completion. I am hoping to work with <code>Content-Length</code> at back end and determine percentage of content loaded at front end.</p>
  
  <p>I am loading a large amount of rows for a grid and need to show incremental progress on UI. Is it possible?</p>
