If data is not in cache it is loaded from server and saved in the cache. Otherwise JClient reads the data from cache.
To redo download from server you can delete existing cache folders. Cache directory can be found in Tools > Preferences > Advanced.

IHistory.getBar(Instrument,Period, OfferSide, int)'s code comments did not indicate reads data from server or cache.
IHistory.getBar(Instrument,Period, OfferSide, int) and IHistory.getBars(Instrument, Period, OfferSide, Filter, long, long) the reads data mode is same?

There are no specific methods to read data from server or cache.
