# Cancel Extended Operation Handler

The Cancel Extended Operation Handler provides support for the LDAP cancel extended operation as defined in RFC 3909.

It allows clients to cancel operations initiated from earlier requests. The property ensures that both the cancel request and the operation being canceled receives response messages.

## Parent

The Cancel Extended Operation Handler object inherits from [Extended Operation Handler](objects-extended-operation-handler.html).

## Cancel Extended Operation Handler properties

You can use configuration expressions to set property values at startup time. For details, see [Property value substitution](expressions.html).
