Description
This rule is not caused by ASL.
ASL is simply reporting when Apache has reported a 503 error. ASL does not cause this to occur, and has no control over these events, it merely reports it.
503 error codes are defined in the RFC as:
"The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response."
Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded.
