the documentation has two entries for validateClient.
validateClient: Enables the validation of client requests using the client fingerprint. Default: true. Validating the client fingerprint minimizes the risk of session hijacking since it’s extremely rare that a hacker’s machine could generate an identical fingerprint number that matches the fingerprint of the client that “lost” the session ID.
validateClient: When set to false, Wisej will not check the client’s IP and user agent when loading the sessions. Default: true.
