My App Server is running an older version of Wildfly (v. 15.0.1.Final). The content served from the server is embedded within a partner site (as an IFrame). This embedded approach stopped rendering on Chrome and Edge recently, while it still works on Firefox. The debugging utilities indicate that the cookie’s SameSite attribute was not set and that it should be set to SameSite=None, which would enable the cross-site operations.
However, I am not sure if there is a way to do this on Wildfly 15. There are instructions online that provide details how to config the Wildfly 19+ (How to set samesite cookie on WildFly 20?) but I couldn't find anything for older versions.
I tried the above and a couple of related suggestions, none worked. Does anyone know if this is possible and if so, how to do it?
