Overview
The ContentUpdateChecker is a module that can be used at the start of a workflow to see if new content is available from either a file or url. If so a log message with event code + the new content is logged, a debug message is logged when no new content is found. In case an empty file is found, the last modification date will be used as content in date format: 'yyyyMMddHHmmss'.
