Module Eliom_common
 :  sig end

Low level functions for Eliom, exceptions and types.

exception Eliom_404

Page not found

exception Eliom_Wrong_parameter

Service called with wrong parameter names

exception Eliom_Session_expired

exception Eliom_Typing_Error of (string * exn) list

The service (GET or POST) parameters do not match expected type

exception Eliom_site_information_not_available of string

That function cannot be used when the site information is not available, that is, outside a request or the initialisation phase of your Eliom module (while reading the configuration file).

In particular, you cannot use the function before the configuration file is read for example when you are using static linking. In that case you must delay the function call using Eliom_service.register_eliom_module .

type cookie_scope = [ `Client_process | `Session ]

Eliom is using regular (browser) cookies but can also use browser tab cookies (only if you are using a client side program)

It is possible to define data tables or service table for one (browser) session, for one tab, or for one group of sessions.

type fullsessionname = cookie_scope * string

module Fullsessionname_Table : sig end

val eliom_link_too_old : bool Polytables.key

If present and true in request data, it means that the previous coservice does not exist any more

val eliom_service_session_expired : (fullsessionname list * fullsessionname list) Polytables.key

If present in request data, means that the service session cookies does not exist any more. The string lists are the list of names of expired sessions
