JSESSIONID questions

We are trying to solve a problem where the keycloak JSESSIONID cookie is colliding with another JSESSIONID cookie. We have tried to change the name of the cookie in Keycloak by using the jboss cli. For example:

I see this command reflected as expected in the standalone.xml file after execution however I do not see a cookie with that name being set in my client app and the JSESSIONID cookie isn’t being set by keycloak either.

Two questions:

  1. Is this the correct way to do this for keycloak?
  2. What is the effect of not having that keycloak JSESSIONID cookie set? My login/logout flows appear to be working correctly.
