Question

I’ve come across a very strange issue. The following jQuery receives an HTTP 405 error code and sends an OPTIONS request method instead of a GET.

function GetPerf() 
{
    jQuery.support.cors = true;
    leInterval = setInterval(function()
    {
    $.ajax({
        url: "http://localhost/PerfMon3/api/performance/categories",
        data: { machine_name : "CLOUDMACHINE" },
        type: "GET",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        xhrFields: {
        withCredentials: true
        },
        success: function (data) {
            WriteResponse(data);
        },
        error: function (x, y, z) {
            alert(data);
        }
    });
    },
    1000)
}

The interesting part is that this works perfectly fine in Internet Explorer, but Chrome I get a 405. Does anyone know what’s going on?

Additional note:
It works perfectly fine regardless of browser when running it from the browser with IIS where the application is hosted. This problem only comes into play from remote machines.

Well, I just love finding out the answer to the issue with my own testing right after asking it on SO. I’m sorry about that, guys.

I changed the url line in the jQuery to

url: "http://cloudmachine/PerfMon3/api/performance/categories"

and now it works perfectly fine.

Still, why did it originally work only in IE? It doesn’t make sense.
