>
> SYNCOPE-15 introduced 'lastChangeDate' and 'creationDate' fields on some
> entities (namely SyncopeUser, SyncopeRole and ExternalResource); such
> information is then transferred to matching TO (e.g. UserTO, RoleTO and
> ResourceTO).
> This means that the respective services (UserService, RoleService and
> ResourceService) could be enhanced in the following way:
> 1. add ETag response header to any method - directly or indirectly via
> Response.Entity - generated from creationDate's or lastChangeDate's value
> 2. implement some "conditional GET" logic: depending on the value of If-*
> request HTTP headers, a value (HTTP status 200) or no value (HTTP status 204)
> will be returned
> 3. with the same idea, implement some "conditional POST/PUT" logic for
> update: an effective update request will be effectively accepted only if
> provided ETag matches the latest modification currently available
