Resolution
Each of them is known issue:
There might be a problem with the keys (1). It can also be caused by a request in http 1.0 (2).
The incoming request URL has a character included in BadUrlChars or BadQueryChars (2)(3)(4)(5).
This will happen if the requested URL is larger than the default value of ACO MaxUrlSize (2).
This is related to a DNS problem. Maybe the request set the IP address instead of the FQDN (2)(6)?
This error happens when the Web Agent doesn't receive the expected data from Apache (7)(8)(9).
