module Netcgi_fcgi:sig..end
 Remark: This connector does not allow requests to be multiplexed
 (and let it know to the web server via FCGI_MPXS_CONNS=0).
 Multiplexing requests is seldom done by
 FastCGI modules and is even sometimes
 impossible because of bugs in them.  Moreover, multiplexing is
 mostly useful if concurrent requests are handled by different
 threads while this library use a single thread to process all
 requests coming on a given connection.  If the need is felt (speak
 out!), a multithreaded connector can be built on the side of this
 one.
class type cgi =object..end
Netcgi.cgi class with FCGI specific methods.
val run : ?config:Netcgi.config ->
       ?allow:(Unix.sockaddr -> bool) ->
       ?output_type:Netcgi.output_type ->
       ?arg_store:Netcgi.arg_store ->
       ?exn_handler:Netcgi.exn_handler ->
       ?sockaddr:Unix.sockaddr -> ?port:int -> (cgi -> unit) -> unitrun f register the function f as a main function of the
      script.  Each call to the script will execute f cgi.  The code
      outside f will be executed only once (when the script is
      loaded into memory) which allows to cache database connections,
      etc.config : Default: Netcgi.default_configallow : Tells whether a connection from the socket is allowed.
                   Default: Use the comma separated list given in the
                   environment variable FCGI_WEB_SERVER_ADDRS or allow all
                   if it does not exist.output_type : Default: `Direct ""arg_store : Default: `Automatic for all arguments.exn_handler : See Netcgi.exn_handler.  Default: delegate
      all exceptions to the default handler.sockaddr : tells on what socket to contact the script.  If
      not specified, the script expects to be launched by the web
      server and to communicate with it through stdin.  For external
      scripts (launched independently of the web server and possibly
      on a different machine), set sockaddr to the address the web
      server needs to connect to to talk to the script (this address
      must also be specified in the wen server config file).port : alternative way to specify sockaddr for localhost
Your application should be ready handle SIGUSR1, used to resquest a "graceful" process shutdown, and SIGTERM to request a quick shutdown.
val handle_request : Netcgi.config ->
       Netcgi.output_type ->
       Netcgi.arg_store ->
       Netcgi.exn_handler ->
       (cgi -> unit) ->
       max_conns:int ->
       log:(string -> unit) option -> Unix.file_descr -> Netcgi.connection_directivehandle_request config output_type arg_store eh f ~max_conns
        ~log fd: This is a lower-level interface that processes
        exactly one request arriving on the existing connection fd.
        max_conns is passed to the FCGI client and indicates how many
        connections this server can process in parallel.
        log is the error logger function or None, in which case
        errors are passed through to the FCGI client.
        The other arguments are just like for run.
        The return value indicates whether the connection can be kept
        open or must be closed.
