AJAX和Web API出现问题

Question

I've build an WebAPI (.net) application and a simple HTML website for the front-end. Everything worked fine when executing via Visual Studio.

When I tried use this application in my host server, I did sucefully send (POST) a complex object via JSON to the webapi (login) and to "GET" complex objects (User info, configurations, etc...)

But, when I tried to perform a "GET" to obtain a list of object, the server respond: 500 - failed to execute 'send' on 'xmlhttprequest': failed to load '<link to my service>'.

In Resume: GET and POST using objects goes fine GET a list of objects goes bad.

What do I do?

CODE:

function GetService(urlFunc) {

var ret = null;

$.ajax({
    url: urlFunc,
    type: 'GET',
    dataType: 'json',
    async: false,
    crossDomain: true,
    success: function (msg) {
        ret = msg;
    },
    error: function (msg) {
        //LOG EVENTS
        ret = false;
    }
});

return ret;

};

I found the problem. Actually it was in the webapi. It was not sending (for some reason) the list in Json. When I changed the type of Return (For an array, by example), the AJAX receive the list normally. Now I have to discover how to config the webapi to send the list of objects. Thanks everyone! I will change the code for remove the async too!
