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.

45  *<pre>
46  *    Expect       =  "Expect" ":" 1#expectation

48  *    expectation  =  "100-continue" | expectation-extension
49  *    expectation-extension =  token [ "=" ( token | quoted-string )

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.
