Send Cookies with CORs (client side only)

send_a_cookie_swagger-ui_index.js

    $(function () {
      // ....
      document.cookie = 'mynameis=cookiemonster'; // I am a Cookie!
      document.cookie = 'mynameis=chocchip'; // I am another Cookie that doesn't overwrite the last one!
      window.swaggerUi = new SwaggerUi({
        url: url,
        dom_id: "swagger-ui-container",
        useJQuery: true,
        authorizations: {
          sendCookies: function() {
            this.xhrFields = {withCredentials: true};
          }
        }
      // ...

The authorizations option is a shortcut version that gives access the each request before executing it.
This is in lieu of

success: function() {
   window.swaggerUi.api.clientAuthorizations.add('someAuth', function() { /* modify request obj */} );
}
