Server.Transfer to an HttpHandler

Question

I have an IHttpHandler with the following ProcessRequest method:

public void ProcessRequest(HttpContext context) {
    int id = Convert.ToInt32(context.Request.QueryString["id"] + 151);
    var xml = XDocument.Parse("<xml><cartid>" + id + "</cartid></xml>");
    context.Response.Write(xml);
}

Which I'm trying to use from an aspx page as follows:

protected void Page_Load(object sender, EventArgs e) {
    order o = new order();
    Server.Transfer(o, false);
}

I get an HttpException: Error executing child request for handler 'PostTest.order'.

If I instead try doing the transfer like:

Server.Transfer("~/order.ashx?id=65", false)

I get an HttpException: Error executing child request for /order.ashx.

Am I doing this wrong or is there another way to accomplish what I want?

Answer 1

Just pass the context:

var handler = new order();
handler.ProcessRequest(Context);
Response.End();
