Upon using the configuration, it is important that any code that sets the `SecurityContextHolder` with a `SecurityContext` also saves the `SecurityContext` to the `SecurityContextRepository` if it should be persisted between requests.

For example, the following code:

.Setting `SecurityContextHolder` with `SecurityContextPersistenceFilter`
====
.Java
[source,java,role="primary"]
----
SecurityContextHolder.setContext(securityContext);
----

.Kotlin
[source,kotlin,role="secondary"]
----
SecurityContextHolder.setContext(securityContext)
----
====

should be replaced with

.Setting `SecurityContextHolder` with `SecurityContextHolderFilter`
====
.Java
[source,java,role="primary"]
----
SecurityContextHolder.setContext(securityContext);
securityContextRepository.saveContext(securityContext, httpServletRequest, httpServletResponse);
----

.Kotlin
[source,kotlin,role="secondary"]
----
SecurityContextHolder.setContext(securityContext)
securityContextRepository.saveContext(securityContext, httpServletRequest, httpServletResponse)
