+### Caching of connection data
+
+The client retrieves the Hive Server connection info from gajumining.com.
+This information is account-specific, and may change over time.
+
+To speed up the reconnecting process, should the Hive Server restart,
+this connection information is cached locally for up to 24 hours.
+The normal place for the cached data would be
+`$ZOMP_DIR//var/uwiger/gmhive_client/Vsn/setup.data/mainnet/gmhc_eureka.XXXXXXXX.cache`,
+where `Vsn` is the current version of `gmhive_client`, and `XXXXXXXX` is a fragment
+of the current account ID. The data location can be changed with the command-line
+option `-setup data_dir Dir`.
