web-server – IIS 7.5 Web日志中的OPTIONS方法到底是什么？

我知道什么是GET和POST,但谷歌几乎不可能选择OPTIONS这个词.这是我所看到的(我删除了最后的所有内容)：

11/23/11    0:02:13 10.100.0.14         GET       /CUpdate2.cshtml  _=1322006533495
11/23/11    0:02:13 10.200.0.10         OPTIONS   /AssignmentCount  _=1322006576798
11/23/11    0:02:13 10.200.0.10         GET       /media/faxSound.wav   -
11/23/11    0:02:13 10.200.0.10         GET       /Star/StarUpdates _=1322006578729
11/23/11    0:02:13 10.100.0.10         GET       /CUpdate2.cshtml  _=1322006533268

查看 this W3 Spec第9.2节：

The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI. This method allows the client to determine the options and/or requirements associated with a resource,or the capabilities of a server,without implying a resource action or initiating a resource retrieval.
