Location: seems inaccurate

[pganti]

Please peruse the response headers here: http://www.webpagetest.org/result/140918.../#request1

The Location header says "Edgecast" which is an error.

Point #1: If you go to maxmind.com and plug that IP 192.33.24.147 it says the owner is Instart Logic. (of course this demo uses their precision service and its possible the geolite free db you have might be out of sync with this)

Point #2 The response header cdn.h should trigger it as instart ({"X-Instart-Request-ID", "instart", "Instart Logic"} but does not do so.

Let me know of any other data points you want me to provide in order to help fix this

http://www.thingsremembered.com is CNAMEd to http://www.adn.9CA5.edgecastcdn.net which is why it is detecting as Edgecast. Even though the script changes the IP the CDN logic still uses the CNAME that came from the DNS lookup.
