When looking at the documentation for Common Application properties, at the Security section, I also found the properties prefixed by spring.session.
In my opinion, the properties related to Spring Session would deserve their own section, as they are not really related to security.
What do you think ?
I found the merge of these properties is done there : https://github.com/spring-projects/spring-boot/blob/master/buildSrc/src/main/java/org/springframework/boot/build/context/properties/DocumentConfigurationProperties.java#L80
