Basic usage involves passing a url and getting a response and data back:

http-options ( url -- response data )

http-options* ( url -- response data )

Advanced usage involves constructing a request, which allows HTTP cookies and HTTP headers to be set:

<options-request> ( url -- request )

RFC2616 does not define any use for an entity body, yet allows for the inclusion of one as part of the OPTIONS method. This is not supported with this version of the http.client. The current implementation of http-options only supports a url request with no corresponding post-data, as per the stack effect.
