Hi, if I want to secure the root directory, namely, when I visit http://localhost:8080/myapp, then it redirects me to the keycloak login page, asking for credentials. How to achieve that?

I modified the Web.xml as follows, but it doesn't secure anything at all. I thought this should work "<url-pattern>/*</url-pattern>", but it doesn't.
