Checks if UNTIL condition is reached. Uses caching result of last Checks if UNTIL condition is reached. Uses caching result of last
comparison of current log file name and target log file name. So cached comparison of current log file name and target log file name. So cached

This caching is needed to avoid of expensive string comparisons and This caching is needed to avoid of expensive string comparisons and
