Resolution
At first glance, 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 (3)(4)(5)(6).
- This will happen if the requested URL is larger than the default value of ACO MaxUrlSize (7).
- This is related to a DNS problem. Maybe the request set the IP address instead of the FQDN (8)(9)?
- This error happens when the Web Agent doesn't receive the expected data from Apache (10)(11)(12).
