js code:
    $.ajax({
        type       : "GET",
        async      : true,
        url        : url,
        contentType: "text/html",
        dataType   : "json",
        beforeSend : function(request) {
            request.setRequestHeader("X-Test-Token", "abc");
        },
        ...
    });
when I get the request headers with cherrypy.request.headers, 
I can't see the "X-Test-Token" in it.
how I can get the custom header in cherrypy?
