Univention Bugzilla – Bug 40297
docs.univention.de doesn't set correct caching headers
Last modified: 2016-03-18 16:31:54 CET
I always need to press F5 so that the content on docs.univention.de gets updated.
As the HTTP response doesn't contain a Cache-Control header caches are allowed to apply a heuristic on how long the content may be cached - The E-Tag and Last-Modified time is therefore ignored as browsers usually don't do conditional requests for long-cacheable resources.
We should allow a maximum cache time of 1 hour?!:
This is noticed recurrently if e.g. new release notes are published and the overview pages still seem to be outdated (for QA or customers). Also manual updates/fixes may not be detected by customers because of caching.
