    If you have control over what verbs the server software allows, then the
    most efficient method is to use the HTTP HEAD method to request headers,
    from which you can extract whatever information about the resource you
    require. To do this, use one of the various INet API's, WinINet, WinHTTP,
    ATL's HttpClient, etc. If you don't have control over the verbs, then most
    likely they're still being allowed as very few people change them.

    For info on the HEAD method, see:
