json url problem

hello
i am using a json file to import some content into a div like this:
$.getJSON('json/main_profile.json', function(data) {
$('#info_title').html(
'<h1>' + "General Information " + '</h1>'
);
});

but the problem appears when i try to replace the json file with a url, like this:
$.getJSON("http://interfaces-server.insource.local/users/145198", function(data) {
$('#info_title').html(
'<h1>' + "General Information " + '</h1>'
);
});

why works with the file but not with the link??

thanks

Do you try to get the JSON file from an external server? Then the script is violating the SOP (same origin policy). You can not get data via AJAX from an external source (different domain than the current page).

what if i do some kind of server authentication... is there a way like that?

Right now you have the following options:

With XMLHttpRequest Level 2 you will be able to have some kind of "trusted server" for your app
