                    When enabled (`True`), the client automatically manages CSRF tokens by

                    Headers are specified as key-value pairs. Note that headers like 'User-Agent'
                    and CSRF-related headers are managed by Prefect and cannot be overridden.

                    Whether the client should check the server's API version on startup.
                    When disabled, the client will skip the call to /admin/version that
                    normally runs once per client context entry.  This is useful for worker
                    subprocesses that inherit a known-compatible server configuration and

                    Warning: setting this value too low may result in data loss as events
                    will be silently dropped when the queue is full.

          description: |2-

                    Controls the activation of CSRF protection for the Prefect server API.

                    When enabled (`True`), the server enforces CSRF validation checks on incoming
                    state-changing requests (POST, PUT, PATCH, DELETE), requiring a valid CSRF
                    token to be included in the request headers or body. This adds a layer of
                    security by preventing unauthorized or malicious sites from making requests on
                    behalf of authenticated users.

                    It is recommended to enable this setting in production environments where the
                    API is exposed to web clients to safeguard against CSRF attacks.

                    Note: Enabling this setting requires corresponding support in the client for
                    CSRF token management. See PREFECT_CLIENT_CSRF_SUPPORT_ENABLED for more.

                    compromise. Adjust this setting based on your specific security requirements

                    that in-memory databases can not be accessed from multiple processes and
                    should only be used for simple tests.
