#Usage: echo https://example.com/index.html|cname-sni > 1.html; firefox 1.html [1]
#where example.com is a site hosted on AWS Cloudfront and the script is called "cname-sni".
#Purpose: send CNAME as SNI hostname, e.g., send dnere6g15e5vs.cloudfront.net instead of www.reuters.com
#Uses DNS-over-HTTPS from Cloudflare but can easily substitute other sources
# echo 104.16.248.249 cloudflare-dns.com >> /etc/hosts
