+A full-featured and extensible Web server
+
+Ocsigen Server implements most features of the HTTP protocol, and has
+a very powerful extension mechanism that makes it very easy to plug
+your own OCaml modules for generating pages. Many extensions are
+already implemented, like a reverse proxy, content compression, access
+control, authentication, etc.
