Module Netcgi_scgi

module Netcgi_scgi: sig .. end

SCGI connector.

The SCGI connects your web applications through a TCP/IP socket (thus the application can run on a machine different from the web server).

See the Setup section at the end of this file to know how to configure your web server.

val run : ?config:Netcgi.config ->
       ?allow:(Unix.sockaddr -> bool) ->
       ?output_type:Netcgi.output_type ->
       ?arg_store:Netcgi.arg_store ->
       ?exn_handler:Netcgi.exn_handler ->
       ?socket:Unix.file_descr ->
       ?sockaddr:Unix.sockaddr -> ?port:int -> (Netcgi.cgi -> unit) -> unit

run f executes f cgi for each SCGI request.

config : Default: Netcgi.default_config

allow : Tells whether a connection from the socket is allowed. Default: allow from all.

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.

socket : is a listening socket to use. Overrides sockaddr and port

sockaddr : The sockaddr for listening. Overrides port

port : The port for listening. Needs to be specified if no sockaddr is passed.

val handle_request : Netcgi.config ->
       Netcgi.output_type ->
       Netcgi.arg_store ->
       Netcgi.exn_handler ->
       (Netcgi.cgi -> unit) ->
       log:(string -> unit) option -> Unix.file_descr -> Netcgi.connection_directive

handle_request config output_type arg_store eh f ~log fd: This is a lower-level interface that processes exactly one request arriving on the existing connection fd.

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.

val handle_connection : Netcgi.config ->
       Netcgi.output_type ->
       Netcgi.arg_store ->
       Netcgi.exn_handler -> (Netcgi.cgi -> unit) -> Unix.file_descr -> unit

handle_connection config output_type arg_store eh f ?script_name fd: This is a lower-level interface that processes exactly one connection fd. The descriptor is closed (even on error).

The other arguments are just like for run.

Setup

Add to httpd.conf or to, say, scgi.conf in /etc/apache/conf.d

    LoadModule scgi_module /usr/lib/apache/1.3/mod_scgi.so
    # Serve the URL /scgi by contacting 127.0.0.1 on port 8888
    SCGIMount /scgi 127.0.0.1:8888
