Hey HN,<p>As part of our mission to maintain transparency, we open sourced our TLS SNI reverse proxy. This uses a LRU cache [1] to improve DNS caching and performance as well as the usual suspects in GoLang for the Go Magic.<p>Every part of the transport in our stack is running on open source now.<p>We hope you all enjoy!<p>[1] <a href="https://github.com/ipv6rslimited/lrucache">https://github.com/ipv6rslimited/lrucache</a>
