Module Eliom_common
module Eliom_common : sig..end
Low level functions for Eliom, exceptions and types.
exception Eliom_404
exception Eliom_Wrong_parameter
Page not found
exception Eliom_Session_expired
Service called with wrong parameter names
exception Eliom_Typing_Error of (string * exn) list
exception Eliom_site_information_not_available of string
The service (GET or POST) parameters do not match expected type
type scope_name = Eliom_common_base.scope_name
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_services.register_eliom_module.

Eliom is using regular (browser) cookies but can also use
browser tab cookies (only if you are using a client side program)
val cookie_scope_of_user_scope : [< user_scope ] -> [> cookie_scope ]
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 : Map.Swith type key = fullsessionname
val eliom_link_too_old : bool Polytables.key
val eliom_service_session_expired :
(fullsessionname list * fullsessionname list)
Polytables.key
If present and true in request data, it means that
the previous coservice does not exist any more
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
