Hi again.

The quotation from RFC about OPTIONS request:

>   Allow, Accept, Accept-Encoding, Accept-Language, and Supported header
>   fields SHOULD be present in a 200 (OK) response to an OPTIONS
>   request.  If the response is generated by a proxy, the Allow header
>   field SHOULD be omitted as it is ambiguous since a proxy is method
>   agnostic.

If Allow header should not be present in proxy's response, then what
should I reply in Accept* headers ? And how to say that this proxy
understands SUBSCRIBE and REGISTER methods, for example ?
