38/**
39 * Defines an interface to verify whether an incoming HTTP request meets
40 * the target server's expectations.
41 *<p>
42 * The Expect request-header field is used to indicate that particular
43 * server behaviors are required by the client.
44 *</p>
45 *<pre>
46 *    Expect       =  "Expect" ":" 1#expectation
47 *
48 *    expectation  =  "100-continue" | expectation-extension
49 *    expectation-extension =  token [ "=" ( token | quoted-string )
50 *                             *expect-params ]
51 *    expect-params =  ";" token [ "=" ( token | quoted-string ) ]
52 *</pre>
53 *<p>
54 * A server that does not understand or is unable to comply with any of
55 * the expectation values in the Expect field of a request MUST respond
56 * with appropriate error status. The server MUST respond with a 417
57 * (Expectation Failed) status if any of the expectations cannot be met
58 * or, if there are other problems with the request, some other 4xx
59 * status.
