Jan Haderka updated MAGNOLIA-2755:
----------------------------------
Description:
The current {{AbstractExecutor.ifModifiedSince()}} method is always returning
true if the request for a cached page includes the '{{If-None-Match}}' header.
The '{{If-None-Match}}' header is/should be set by the browser as a request
header if the prior response for a page/resource included the Etag header,
which all 'docroot' cached responses from Magnolia (on Tomcat) do.
Rather than returning '{{true}}' to the {{IfModifiedSince()}} method, if the
'{{If-None-Match}}' header is present in the request, the cache should compare
its value with that of the 'Etag' header that is stored with the CachedPage
headers. If the ETag header is not present, the cache should fall back on last
modified date.
N.B. the Etag header being added to 'docroot' resources e.g. css/js/images etc.
It is not added for Magnolia repository managed content.
