option updateCache to LL::NG::Common::Session::update
It would be usefull to have an option updateCache to LL::NG::Common::Session::update, that would be
- -1 in order not to update cache
- 0 in order to update cache only on the current server (this is the current behaviour)
- 1 in order to update cache on all servers
- 2 in order to update cache on the current server but not session backend (for local macros)
It would allow to insert local macros with a high-level function, insead of handling session cache by hand, as now (by the way, this makes cached objects unavailable - well, this is a bug).
The way to implement updateCache = 1 was discussed in ##712 (closed).
