# TODO While some of the pattern groups such as command injection are usually
#      safe of false positives, other pattern groups such as SQL injection and 
#      XSS may require setting exceptions and therefore are set to log only by
#      default. 
#
#      Start ModSecurity in monitoring only mode and check whether your 
#      application requires exceptions for a specific URL, Pattern or source IP
#      before moving to blocking mode.
