manager: API: cache clearance implementation via HTTP API
Clearing the resolvers cache is possible by connecting to running kresd
using its unix domain socket and calling cache.clear().
Starting with version 6, it would be nice to be able to clear the cache via the HTTP management API and the kresctl
tool.
For example:
$ kresctl cache-clear # like 'cache.clear()', removes max. 100 records by default
$ kresctl cache-clear --name example.net. # and so on with other 'cache.clear()' parameters
