SameSite cookie setting added for Mashup support in Google Chrome v80+
Resolved in Pega Version 8.3.2
The Google Chrome browser version 80 and above now treats SameSite with a blank value as "Lax" by default, causing mashup scenarios to break. In order to compensate for this change, support has been added for setting SameSite=None in Cookie Settings in the CSRF LP (DevStudio-> System-> Setting-> CrossSiteRequestForgery) which will enforce HTTPS for the Pega server and mashup. Note: The SameSite cookie may be set to None/Lax/Strict, based on the requirement. For mashups to work, SameSite should be set as None. To follow proper security standards, it should be set as Strict.
