Setting a timeout for ServerXMLHTTP request

Question

Does anyone know how to set up set up a default action for when a ServerXMLHTTP request times out? I'm using setTimeouts() to set the time out options according to the MSDN site.

Ideally I would like to initialize the request again from the beginning or refresh the page should it time out.

I'm using classic asp and jscript.

Here's my request:

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

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

    // 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;
    }
}

Answer 1

The important thing is to find out why it is timing out ..

Is the remote Url on the same application as the calling page ?

if so have a look at INFO: Do Not Send ServerXMLHTTP or WinHTTP Requests to the Same Server as you will be facing thread starvation ..

Figured it out. I just need to use a try/catch statement.

function serverXmlHttp(url) {

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

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

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

        if (serverXmlHttp.readyState == 4) {
            return serverXmlHttp.responseText;
        }
    catch(error) {
        // whatever I want to happen if there's an error
        Response.Write("Sorry, your request has timed out");
    }

}
