How to use FileUltimate with a croos domain
Question asked by Alejandro Mares - 1/9/2020 at 9:57 AM
I want to use FileUltimate in a Cross Domain escenario, but I'm not sure how to do it.

On the first tough I´m using an iframe, on the client Domain, it start a refresh page like this:

Request Headers:

Response Headers:
 BTW: I own both Domains 

The Domains are on separate webservers.

It looks iike the iframe cross domain its not possible.... or else.

Any idea on how to deal with it?

This problem start with an update of Chrome, Firefox and InternetExplorer, with older browsers the behavior is diferent.

It seems this is related to a recent .NET Framework change:

If the application targets the .NET Framework 4.7.2 or later versions, the default value is Lax; otherwise, the default value is None.
And from your response headers, I see that the cookie has "SameSite=Lax" attribute.

You can go back to previous behavior by setting this in your Web.config:

  <sessionState cookieSameSite="None" />
