package AWS.Services.Dispatchers with Pure is
-- Services on the Dispatcher tree are to help building big servers.
-- Experiences shows that a lot of user's code is to check the value of a
-- specific URI or request method to call the right callback that will
-- handle the request. This code is a big "if/elsif/end if" that just hide
-- the real job. A dispatcher is to replace this code. Currently there is
-- five of them:
--
-- URI (AWS.Services.Dispatchers.URI)
-- to dispatch to a callback depending of the resource name.
--
-- Method (AWS.Services.Dispatchers.Method)
-- to dispatch to a callback depending of the request method.
--
-- Virtual_Host (AWS.Services.Dispatchers.Virtual_Host)
-- to dispatch to a callback depending on the host name. This is known
-- as virtual hosting and permit to have multiple servers on the same
-- machine using the same port.
--
-- Transient_Pages (AWS.Services.Dispatchers.Transient_Pages)
-- to handle transient pages, if the default user's callback returns
-- 404 this dispatcher checks if the requested resource is a transient
-- page.
--
-- Timer (AWS.Services.Dispatchers.Timer)
-- to dispatch to a specific callback depending on the current time.
--
-- Linker (AWS.Services.Dispatchers.Linker)
-- to link two dispatchers together, if the first one retruns 404 tries
-- the second one.
