Pangolin is an open-source, self-hosted tunneled reverse proxy server that brings identity-aware access control and dashboard management to exposing private services securely. It allows you to connect applications and resources behind firewalls or NATs to a central hub, using encrypted tunnels rather than opening public ports or relying entirely on VPNs. With Pangolin you can route traffic from across distributed networks, enforce contextual access rules (such as SSO, geolocation, time of day, IP restrictions), and manage all of your exposed resources in one dashboard. It supports multi-site deployments and highly-available node architectures, enabling you to own your infrastructure yet still get orchestration and control benefits. Pangolin works well for individuals, teams or organizations that need to expose internal web apps, APIs, or services, while maintaining strong authentication, auditing and governance.

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.
