The connection between apache/mod-mono and mod-mono-server uses named
pipe(s). You can also use TCP/IP if you want to run mod-mono-server in a
different machine, but that's not the default.
mod-mono-server(2) and xsp(2) are basically the same thing, only that
mod-mono-server gets its input from a named pipe and xsp gets it
directly from a TCP socket.

(replace IIS with apache and aspnet_isapi.dll with mod-mono).
