It should be noted that the most recent versions of PhantomJS (1.5+) do not support the Adobe Flash browser plug-in. To address this potential limitation, I conducted testing with an older version of PhantomJS (1.4) and Flash. The inclusion of Flash led to much higher resource utilization, instability, and introduced a large performance penalty. While this method successfully analyzed Flash requests, I determined that Flash elements were comparatively rare and had negligible effect on the top-level trends presented below. Therefore, I made the decision to forgo analysis of Flash requests in favor of greater software reliability by using the most recent version of PhantomJS (1.9).
