Network Firewall uses the token to ensure that the policy hasn't changed since you last retrieved it. If it has changed, the operation fails with an <code>InvalidTokenException</code>. If this happens, retrieve the firewall policy again to get a current copy of it with current token. Reapply your changes as needed, then try the operation again using the new token. </p>"
