 The servlet auto-configuration replaces the need to use `@Enable*HttpSession`.
 
-If a single Spring Session module is present on the classpath, Spring Boot uses that store implementation automatically.

 You can take control over Spring Session's configuration using `@Enable*HttpSession` (servlet) or `@EnableRedisWebSession` (reactive).
 This will cause the auto-configuration to back off.
-Spring Session can then be configured using the annotation's attributes rather than the previously described configuration properties.
+Alternatively, depend on the relevant Spring Session module directly rather than using one of Spring Boot's starters for Spring Session.
