Field Summary

Fields

Modifier and Type	Field and Description
static String	CONNECTION_TIMEOUT Determines the timeout in milliseconds until a connection is established.
static String	LST_IO_THREADS Defines the IO threads to be used for dedicated NIO operations.
static String	SND_IO_THREADS Defines the IO threads to be used for dedicated NIO operations.
static String	SO_LINGER Sets SO_LINGER with the specified linger time in seconds.
static String	SO_TIMEOUT Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets).
static String	SOCKET_BUFFER_SIZE Determines the size of the internal socket buffer used to buffer data while receiving / transmitting HTTP messages.
static String	STALE_CONNECTION_CHECK Determines whether stale connection check is to be used.
static String	TCP_NODELAY Determines whether Nagle's algorithm is to be used.

Field Detail

SND_IO_THREADS

public static final String SND_IO_THREADS

Defines the IO threads to be used for dedicated NIO operations. Typically the number of CPU cores

See Also:

Constant Field Values

LST_IO_THREADS

public static final String LST_IO_THREADS

Defines the IO threads to be used for dedicated NIO operations. Typically the number of CPU cores

See Also:

Constant Field Values

SO_TIMEOUT

public static final String SO_TIMEOUT

Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets). A timeout value of zero is interpreted as an infinite timeout.

This parameter expects a value of type Integer.

See Also:

SocketOptions.SO_TIMEOUT, Constant Field Values

TCP_NODELAY

public static final String TCP_NODELAY

Determines whether Nagle's algorithm is to be used. The Nagle's algorithm tries to conserve bandwidth by minimizing the number of segments that are sent. When applications wish to decrease network latency and increase performance, they can disable Nagle's algorithm (that is enable TCP_NODELAY). Data will be sent earlier, at the cost of an increase in bandwidth consumption.

This parameter expects a value of type Boolean.

See Also:

SocketOptions.TCP_NODELAY, Constant Field Values

SOCKET_BUFFER_SIZE

public static final String SOCKET_BUFFER_SIZE

Determines the size of the internal socket buffer used to buffer data while receiving / transmitting HTTP messages.

This parameter expects a value of type Integer.

See Also:

Constant Field Values

SO_LINGER

public static final String SO_LINGER

Sets SO_LINGER with the specified linger time in seconds. The maximum timeout value is platform specific. Value 0 implies that the option is disabled. Value -1 implies that the JRE default is used. The setting only affects the socket close operation.

This parameter expects a value of type Integer.

See Also:

SocketOptions.SO_LINGER, Constant Field Values

CONNECTION_TIMEOUT

public static final String CONNECTION_TIMEOUT

Determines the timeout in milliseconds until a connection is established. A timeout value of zero is interpreted as an infinite timeout.

This parameter expects a value of type Integer.

See Also:

Constant Field Values

STALE_CONNECTION_CHECK

public static final String STALE_CONNECTION_CHECK

Determines whether stale connection check is to be used. The stale connection check can cause up to 30 millisecond overhead per request and should be used only when appropriate. For performance critical operations this check should be disabled.

This parameter expects a value of type Boolean.

Constant Field Values
