JSONP request: "Resource interpreted as Script but transferred with MIME type text/html"

Question

I'm trying to do my first cross request with JSONP to get a banner from an external URL.

<script type="text/javascript">
    function handleResponse(json){
    var data = JSON.parse(json);
    alert(data);
    }
</script>
<script src="http://lujanventas.com/plugins/banners/?callback=handleResponse"></script>

This code I think it's a pretty basic JSONP request. My problem is that is that I get the error: "Resource interpreted as Script but transferred with MIME type text/html".

I haven't modified the file in any way to prepare it for the request. (I believe I must modify it somehow but have no idea what to do).

What must I do to get the file with no problems?

Are you sure that there is a JSONP service on that site? It doesn't look like it. — user123444555621, May 31 '12 at 03:57
http://lujanventas.com/plugins/banners is an html website. Adding callback to a url does not make it jsonp — austinbv, May 31 '12 at 03:59

@Pumbaa80 they are not about the same issue. I first wanted to do it with CORS but abandoned it since not being not cross-browser compatible. And I'm now considering an iframe as last resource. — lisovaccaro, May 31 '12 at 04:16

I had the same issue with my jsonp requests. I got

Resource interpreted as Script but transferred with MIME type text/plain

, but once I set the response "Content-Type" header to "text/javascript", I get it resolved. But this could only be done if you control the server. So either tell lujanventas.com to try to change the "ContentType" header, or ignore it :)

Cheers!
