Feature #17509
Updated by Mathias Schreiber over 9 years ago
The page preview works by sending the parameter no_cache=1 in the URL. This parameter is often abused by extensions. It should be removed/disabled for use in extensions. To prepare the removement of this parameter a change of the BE preview mechanism is required. There may be different options: a) The parameter no_cache=1 only works if a BE user is logged in. b) Use of an alternative parameter, that is limited to the BE. How could such a limitation be done? In case of a) it's the identical measure as the general disabling of the the no_cache parameter. Related: 0005517, 0005332 (issue imported from #M6108)
