Subject: Possible "fix" for wrong cache key:
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=a81aabdb6ae5f7109cb388a1c92a3e8698b57cad;p=hub.git

Possible "fix" for wrong cache key:
- $onlyKeys allows to set database table columns that shall be used for
  creating a cache key, this can be used to look for a node id/ip/port
  combination instead of the default session id.
