Extends the logfile plugin sntax to accept a key value string. Supported values are: - logfile, the actual file name of the log file (mandatory) - backupname, the file name of the rotated log - maxsize, the size in bytes that triggers rotation maxsize is mandatory if you want rotation, if you omit backupname the logfile with a timestamp appended would be used as file name. Example: logger = staticlogger file:logfile=%dstatic.log,backupname=%dstatic.log.old,maxsize=1500 log-route = staticlogger app: -1|req: -1 will create a file based logger called static logger that would log all the static requests to a file called static.log, which would be rotated each 1500 bytes to a file named static.log.old Fixes #542
