The SameSite cookie attribute controls how the browser sends third-party cookies (also referred to as cross-site or cross-origin cookies). By default, SameSite cookies are set to "Lax".
If your solution includes embedding content from the Web Server into another web application in a different domain, you must configure the Web Server to instruct the browser to send cookies across domains by modifying the SameSite cookie attribute to have a value of "SameSite=None".
This setting is standard in version EP1 and greater.
