Module Eliom_registration.​String_redirection

module String_redirection : sig..end

Eliom service registration for services that returns a redirections towards a string-URL. See the Eliom manual for more information about Redirections outputs. The URL given must be an absolute URI.

The default returned HTTP code is 302 Found. You could use the optional parameter ~options to change this value, see Redirections for a detailled description.

This an instance of the Eliom_registration.​Registration abstract signature.


Service registration

val register : 
  ?scope:[< Eliom_common.scope ] ->
  ?options:[ `Found
   | `MovedPermanently
   | `NotNodifed
   | `SeeOther
   | `TemporaryRedirect
   | `UseProxy ] ->

   [< Eliom_service.suff ], 'gn, 'pn, [ `Registrable ],
   [< Eliom_service.non_ocaml_service ])
   Eliom_service.service ->
  ?error_handler:((string * exn) list -> Eliom_lib.Url.uri Lwt.t) ->
  ('get -> 'post -> Eliom_lib.Url.uri 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_scope by default, see the Eliom manual for detailled description of different scope.

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_scope. 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 secure state.

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_Errorl).
