Open Source BSD Reverse Proxy Servers

Caddy is a powerful, extensible, enterprise-ready server platform that uses TLS by default. Everything you would require in your infrastructure, from TLS certificate renewals and OCSP stapling, to reverse proxying and ingress, Caddy simplifies it all. Its modular architecture lets you do more with just a single static binary that compiles for any platform. Caddy is the only web server that uses HTTPS automatically and by default. It automatically renews TLS certificates, staples OCSP responses and more. Though used mostly as an HTTPS server, Caddy can be used to run Go applications, offering automated documentation, graceful on-line config changes via API and more to these apps. Caddy is very extensible, with a powerful plugin system unlike any other web server.

Apache2::ModProxyPerlHtml is the most advanced Apache output filter to rewrite HTTP headers and HTML links for reverse proxy usage. It is written in Perl and exceeds all mod_proxy_html.c limitations without performance lost. It is very simple and has far better parsing/replacement of URL than the original C code. It also support meta tag, CSS, and javascript URL rewriting and can be use with compressed HTTP. You can now replace any code by other, like changing images name or anything else. mod_proxy_html can't do all of that. Since release 3.0 ModProxyPerlHtml is also able to rewrite HTTP headers with refresh url redirection. One of the common used of ModProxyPerlHtml is as free replacement for ISA servers.
