Questions about finding Amazon CloudFront

How does PageSourceSearch know a website uses Amazon CloudFront?
By the source itself: Assets served from a CloudFront distribution use a <id>.cloudfront.net hostname. PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
Is this a complete list of websites using Amazon CloudFront?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 132,995 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
How do I find websites that use Amazon CloudFront together with another technology?
Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example cloudfront.net/ with wp-content/plugins/ lists the WordPress sites that use Amazon CloudFront.
