asp-classic – 为ServerXMLHTTP请求设置超时

理想情况下,我想从头开始再次初始化请求,或者如果超时则刷新页面.

我正在使用经典的asp和jscript.

这是我的要求：

function serverXmlHttp(url) {
    var serverXmlHttp;
    serverXmlHttp = Server.CreateObject("Msxml2.ServerXMLHTTP.6.0");

    // set time out options
    serverXmlHttp.setTimeouts(15000,15000,15000);

    // does not work
    // serverXmlHttp.ontimeout(Response.Write("page has timed out"));

    serverXmlHttp.open("GET",url,false);
    serverXmlHttp.send();

    if (serverXmlHttp.readyState == 4) {
        return serverXmlHttp.responseText;
    }
}
