hapi pre-response handler to include Accept in the Vary header
Table of Contents
Motivation
Google Chrome caches only the last response for any endpoint, regardless of
content-type, which results in rendering json data instead of the rendered
page based on the html representation. These values are cached even with the
Cache-Control header set to no-cache in order to optimize operations like
navigating back or duplicating a tab.
While normally unnecessary because of configuring the headers to prevent
caching,including Accept in the Vary header does technically further inform
a client that a single endpoint responds with different responses based on the
Accept header of the request.
