Fournir un entête HTTP Last-updated ( ou etag )

Une URL de données , telle que
http://semantic-bus.org/data/api/PWA_All
devrait renvoyer un entête HTTP Last-updated ( ou etag ).

Cela permettra à des outils clients et cache, tel que Semantic_Forms, de recharger un URL SB uniquement s'il est mis à jour .

Start by tracing how the data URL http://semantic-bus.org/data/api/PWA_All is served and where its HTTP response headers are assembled. Check how Semantic_Forms or similar clients use the response, then verify that unchanged data can be identified through Last-updated or an ETag and that updated data produces a new cache indicator.
