hi @christophstrobl, where were these links found?

Reference docs links published at https://spring.io/projects/spring-framework#learn, are of the form:

https://docs.spring.io/spring-framework/docs/6.0.0/reference/html/core.html#context-functionality-events
https://docs.spring.io/spring-framework/docs/6.0.0/reference/html/web.html#mvc-cors

and I don't see the 3rd one web.html#controller-method-cors-configuration in 6.0.0 docs ?

We don't find them. We generate them in our reference docs using the Spring version number our project builds refer to, to make sure we link a matching Spring reference documentation version.
