Active rule currently published.
ASL does not cause this event.
ASL is simply reporting when apache reports that a client has requested part of a file, document, etc. that is invalid. For example, the client asked for the 1800th-1900th bytes of a document, but the document was only 200 bytes long. This may indicate an attempt to carry out a denial of service attack, or the client may simply be trying to access files that have changed in size since the last request and client is using out of date cached data.
This rule does not block anything by default.
