    // Check the revocation status of the SSL server certificate for chilkatsoft.com
    var status: Int = http.ocspCheck("chilkatsoft.com", port: 443).intValue

    print("chilkatsoft.com status = \(status)")

    // The status can have 4 values:
    // -1: Unable to check because of an error.
    //  0: Good
    //  1: Revoked
    //  2: Unknown

    if status < 0 {
        print("\(http.lastErrorText!)")
    }

    // Now check the status for a revoked server certificate.
    status = http.ocspCheck("revoked.badssl.com", port: 443).intValue

    print("revoked.badssl.com status = \(status)")
