Chart DataSource 401 Unauthorized

[Lyle 3M]

I have a page with a chart on it that works great on most browsers I've tried.  However, when I run this page on an iPad, then the fetch data fails with an Unauthorized exception.  I've logged on and the authorization cookie should be send to my MVC WebAPI page which is secured to authorized users only.  Is there some way to ensure that the proper cookies are sent with each request?

Thanks!

Hello Lyle,

If the cookie is sent with regular $.ajax request then it should be also sent when the dataSource.read is being called.

On a side note you can send additional parameters to the server with the help of the data function or by passing an object literal to the dataSource.read method.

I could suggest you to search the internet for similar issues.
