http_filter is an HTTP tunnel with filtering and multiplexing. It runs on a firewall, sitting in front of not-so-secure Web servers (like IIS), and it accepts requests, applies a set of rules to them, and allows the requests to be passed through to the back-end Web server only if they pass all filters. The rules can be defined globally or per-server.
