How CDN detection works in webpgatest
I did some performance optimization (and I test it with webpagetest.org) but I still have problem with CDN detection. It looks like on screen:
All requests (except first which is http request for html) with red X icon in last column are:
- for assets (css, js, images or fonts)
- from same domain (different than main application domain)
What should I do to have assets detected as CDN on this test???
Solution
WebPageTest just uses a list of the most common CDN providers and then parse the assets request header :
CDN_PROVIDER_HEADER cdnHeaderList[] = {
{"server", "cloudflare", _T("Cloudflare")},
to check (in this case) if there is a server key containing cloudflare.
