        if ( req.http.host ~ "^xxx.com") {        set req.backend = www;        }        else        {        error 404 "not allowed hostname";        }
        if (req.request == "GET" && req.url ~ "\.(js|css|jpg|png|gif|swf|jpeg|ico)$") {        unset req.http.cookie;        }
        if (req.request != "GET" && req.request != "HEAD") {        return (pass);        }        if (req.http.x-forwarded-for) {        set req.http.X-Forwarded-For = req.http.X-Forwarded-For ", " client.ip;        }        else {        set req.http.X-Forwarded-For = client.ip;        }
