Repro Steps:

You’ll need to:

  • Have a web service that returns JSON of a substantial size (500K plus);
  • Have a client page that calls this service asynchronously using an xmlHTTPRequest, AND that is running process (such as an AJAX load indicator) which you can observe.

Expected Results:

I expect the UI to NOT hang during decompression of compressed AJAX result sets.

Actual Results:
