| /** |
| * Defines an interface to verify whether an incoming HTTP request meets |
| * the target server's expectations. |
| *<p> |
| * The Expect request-header field is used to indicate that particular |
| * server behaviors are required by the client. |
| *</p> |

| * expect-params = ";" token [ "=" ( token | quoted-string ) ] |
| *</pre> |
| *<p> |
| * 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. |
