Module Action
 :  sig end

Eliom service registration for services that only execute actions. See the Eliom manual for more information about .

If you give the optional parameter ~options:`NoReload to the registration function, the action will executed and a 204 No Content will be sent to the server.

This an instance of the Eliom_registration.Registration abstract signature.

=== Service registration ===

val register : ?scope:[< Eliom_common.scope ] -> ?options:[ `NoReload | `Reload ] -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Http_headers.t -> ?secure_session:bool -> service:('a, 'b, [< Eliom_service.internal_service_kind ], [< Eliom_service.suff ], 'c, 'd, [ `Registrable ], Eliom_registration.http_service) Eliom_service.service -> ?error_handler:((string * exn) list -> unit Lwt.t) -> ('a -> 'b -> unit Lwt.t) -> unit

The function register service handler will associate the service to the function handler . The handler function take two parameters, the GET and POST parameters of the current HTTP request, and should returns the corresponding page.

The optional parameter ~scope is Eliom_common.global by default, see the Eliom manual for detailled description .

The optional parameter ~options is specific to each output module, see the type description for more information.

The optional parameters ?charset , ?code , ?content_type and ?headers can be used to modify the HTTP answer sent by Eliom. Use this with care.

The optional parameter ~secure_session has no effect for scope Eliom_common.global . With other scopes, the parameter is used to force the session service table in which the handler will be registered. By default, the service is registred in the unsecure session if the current request's protocol is http , or in the secure session if the protocol is https . If set to false (resp. true ) the handler will be stored in the unsecure (resp. secure) session. See the Eliom manual for an introduction to .

The optional parameter ~error_handler is used to specialize the error page when actual parameters aren't compatible with the expected type. The default error handler is fun l -> raise ( Eliom_common.Eliom_Typing_Error l) .

=== Low-level function ===

val send : ?options:[ `NoReload | `Reload ] -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Http_headers.t -> unit -> (Eliom_registration.browser_content, Eliom_registration.http_service) Eliom_registration.kind Lwt.t

The function send page build the HTTP frame corresponding to page . This may be used for example in an service handler registered with Eliom_registration.Any.register or when building a custom output module.
