Cisco Bug: CSCul99538 - ERS wrongly returns "HTTP version not supported" in other cases

1.2(0.899)

Description (partial)

Symptom:
If you send an "Expect : 100" header in the HTTP request, ISE will respond with a 505 HTTP version not supported.
Of course the "Expect" header is the cause of the problem, but ISE should return a more meaningful error message because in this case the HTTP version was 1.1 and fully supported.
