There isn't an option to add to a domain cookie with the attribute "SameSite=None". The value "None" which appears as an option is used will not add the attribute at all.


You are unable to set SameSite=None


You want to have SameSite=none attribute added to a domain cookie.


Set the SameSite=None cookie value in the application. An iRule could also be added that inserts the cookie. For more information on the iRule, see the following DevCentral article: https://devcentral.f5.com/s/articles/iRule-to-set-SameSite-for-compatible-clients-and-remove-it-for-incompatible-clients-LTM-ASM-APM
