/*
 * Description: Assigns a custom message to the rule or chain in which it
 * appears. The message will be logged along with every alert.
 *
 * Action Group: Meta-data
 *
 * Example:
 * SecRule &REQUEST_HEADERS:Host "@eq 0" "log,id:60008,severity:2,msg:'Request Missing a Host Header'"
 *
 * Note  : The msg information appears in the error and/or audit log files
 *         and is not sent back to the client in response headers.
 *
 * Note 2: The msg action can appear multiple times in the SecRule, however
 *         just the last one will be take into consideration.
