pixelserv-tls is a tiny bespoke HTTP/1.1 webserver with HTTPS and SNI support. It acts on behalf of hundreds of thousands of advert/tracker servers and responds to all requests with nothing to speed up web browsing. pixelserv-tls supports TLSv1.0, TLSv1.2 and TLSv1.3 and thus could operate with a wide range of browsers and client devices. Server certificates for any given advert/tracker domains are generated automatically on first use and saved to disk.
