JQuery $.post cross domain and credentials

Question

I have written a web application which uses lot\'s of $.post calls with JQuery. Now I would like to send withCredentials: true with it to keep a sessio

Answer 1

You can use jQuery.ajaxSetup() to set default options that each ajax request will use (including $.post and $.get)

$.ajaxSetup({
    crossDomain: true,
    xhrFields: {
        withCredentials: true
    },
    username: 'test',
    password: 'test'
});

$.post('http://example.com/server/api.php', {
    username: 'test',
    password: 'test'
}, function (d) {
    $('body').html(d.status);
}, 'json');

Also the warning regarding this API

Note: The settings specified here will affect all calls to $.ajax or Ajax-based derivatives such as $.get(). This can cause undesirable behavior since other callers (for example, plugins) may be expecting the normal default settings. For that reason we strongly recommend against using this API. Instead, set the options explicitly in the call or define a simple plugin to do so.
