Well It Worked On My Machine (and the target host)

If you’re doing jQuery/AJAX –> web service kinda things like this:

function submitWooshTest() {
    var adslOrderID = gQs.get("orderid");

    $.ajax({
        type: "POST", url: "ScriptServices/WooshTester.asmx/RequestWooshTest",
        data: {
            adslOrderID: adslOrderID,
            faultType: $('#wooshFaultType').val(),
            hasWorked: $('#wooshHasWorked').is(':checked'),
            disruptive: $('#wooshDisruptive').is(':checked'),
            faultDate: $('#wooshFaultDate').val(),
            faultTime: $('#wooshFaultHour').val() + ':' + $('#wooshFaultMinute').val()
        },
        success: function(result) {
            $.unblockUI();
            $.blockUI({ message: $('#wooshResults') });
            showWooshTests();
        },
        error: function(x, s, e) {
            debug(x, s, e);
        }
    });
}

And the web service end point looks like:

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public int RequestWooshTest(int adslOrderID, string faultType, bool hasWorked, bool disruptive, string faultDate, string faultTime)
{
// etc
}

Don’t forget to configure your web services protocols in your web.config:

<?xml version="1.0"?>
<configuration>
    <system.web>
        <webServices>
            <protocols>
                <add name="HttpGet"/>
                <add name="HttpPost"/>
            </protocols>
        </webServices>
    </system.web>
</configuration>

Otherwise when accessing your functionality from a browser that isn’t on the localhost you’ll get the following cryptic error message:

System.InvalidOperationException: Request format is unrecognized for URL unexpectedly ending in '/RequestWooshTest.

[InvalidOperationException: Request format is unrecognized for URL unexpectedly ending in '/RequestWooshTest.]
