| A server that does not understand or is unable to comply with any of |
| the expectation values in the Expect field of a request MUST respond |
| with appropriate error status. The server MUST respond with a 417 |
| (Expectation Failed) status if any of the expectations cannot be met |
| or, if there are other problems with the request, some other 4xx |
| status. |
