    • Method Detail

      • getAcceptBacklog

        Gets the "accept-backlog" property.

        Specifies the maximum number of pending connection attempts that are allowed to queue up in the accept backlog before the server starts rejecting new connection attempts.

        This is primarily an issue for cases in which a large number of connections are established to the server in a very short period of time (for example, a benchmark utility that creates a large number of client threads that each have their own connection to the server) and the connection handler is unable to keep up with the rate at which the new connections are established.

        Default value: 128

        Returns:
        Returns the value of the "accept-backlog" property.

      • setAcceptBacklog

        void setAcceptBacklog​(ValueOrExpression<Integer> value)

        ValueOrExpression<Boolean> isUseTcpKeepAlive()
        Gets the "use-tcp-keep-alive" property.

        Indicates whether the HTTP Connection Handler should use TCP keep-alive.

        If enabled, the SO_KEEPALIVE socket option is used to indicate that TCP keepalive messages should periodically be sent to the client to verify that the associated connection is still valid.

        Default value: true

        Returns:
        Returns the value of the "use-tcp-keep-alive" property.

      • setUseTcpKeepAlive

        ValueOrExpression<Boolean> isUseTcpNoDelay()
        Gets the "use-tcp-no-delay" property.

        Indicates whether the HTTP Connection Handler should use TCP no-delay.

        If enabled, the TCP_NODELAY socket option is used to ensure that response messages to the client are sent immediately rather than potentially waiting to determine whether additional response messages can be sent in the same packet. In most cases, using the TCP_NODELAY socket option provides better performance and lower response times, but disabling it may help for some cases in which the server sends a large number of entries to a client in response to a search request.

        Default value: true

        Returns:
        Returns the value of the "use-tcp-no-delay" property.

        void setUseTcpNoDelay​(ValueOrExpression<Boolean> value)
               throws PropertyException
        Sets the "use-tcp-no-delay" property.

        Indicates whether the HTTP Connection Handler should use TCP no-delay.

        If enabled, the TCP_NODELAY socket option is used to ensure that response messages to the client are sent immediately rather than potentially waiting to determine whether additional response messages can be sent in the same packet. In most cases, using the TCP_NODELAY socket option provides better performance and lower response times, but disabling it may help for some cases in which the server sends a large number of entries to a client in response to a search request.

        Parameters:
        value - The value of the "use-tcp-no-delay" property.
        Throws:
        PropertyException - If the new value is invalid.
