type Netcgi_apache.Apache.Request.t -> result 
The type of handler functions.  The exception Exit is
        considered as a normal way of terminating early.  All other
        exceptions are logged and result in an Internal_server_error
        response by Apache.
val register : t -> string -> unit
Modules may call register fn name to register one or more
        handler functions.  The handler functions are then referred to
        in the Netcgi*Handler configuration commands as
        Module_name.name where Module_name is derived from the
        filename (given to the NetcgiLoad directive) and name is the
        string passed here.
