I subscribe to the “On the Web” calendar https://mail.aegee.org/calendar/AllAegeeEvents.ics in Evolution. Then I click in the Calendar view on “Refresh”. WEBCAL_DEBUG=1 evolution-calendar-factory -r prints:

Since the server returns ETag and Last-Modified headers, EDS shall memorize them and on subsequent GET shall send If-None-Match and If-Modified-Since headers (or at least one of those, if both are present).

Is the GET content not logged, because it is gzip-encoded, or for other reasons?
