+==== HTTP HEAD and HTTP OPTIONS
+
+`@RequestMapping` methods mapped to "GET" are also implicitly mapped to "HEAD",
+i.e. there is no need to have "HEAD" explicitly declared. An HTTP HEAD request
+is processed as if it was an HTTP GET except instead of writing the body only
+the number of bytes are counted and the "Content-Length" header set.

+`@RequestMapping` method have built-in support for HTTP OPTIONS. By default an
+HTTP OPTIONS request is handled by setting the "Allow" response header to the
+HTTP methods explicitly declared on all `@RequestMapping` methods with matching
+URL patterns. When no HTTP methods are explicitly declared the "Allow" header
+is set to "GET,HEAD". Therefore it's highly recommended to always explicitly
+declare the HTTP method(s) an `@RequestMapping` method is meant to handle.
+
+Although not necessary an `@RequestMapping` method can be mapped to and handle
+either HTTP HEAD or HTTP OPTIONS, or both.
