Field Summary

static String	CONNECTION_TIMEOUT Deprecated. Determines the timeout in milliseconds until a connection is established.
static String	MAX_HEADER_COUNT Deprecated. Determines the maximum HTTP header count allowed.
static String	MAX_LINE_LENGTH Deprecated. Determines the maximum line length limit.
static String	MIN_CHUNK_LIMIT Deprecated. Defines the size limit below which data chunks should be buffered in a session I/O buffer in order to minimize native method invocations on the underlying network socket.
static String	SO_KEEPALIVE Deprecated. Defines whether or not TCP is to send automatically a keepalive probe to the peer after an interval of inactivity (no data exchanged in either direction) between this host and the peer.
static String	SO_LINGER Deprecated. Sets SO_LINGER with the specified linger time in seconds.
static String	SO_REUSEADDR Deprecated. Defines whether the socket can be bound even though a previous connection is still in a timeout state.

Field Detail

SO_TIMEOUT

static final String SO_TIMEOUT

Deprecated.

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

static final String TCP_NODELAY

Deprecated.

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

static final String SOCKET_BUFFER_SIZE

Deprecated.

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

static final String SO_LINGER

Deprecated.

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

SO_REUSEADDR

static final String SO_REUSEADDR

Deprecated.

Defines whether the socket can be bound even though a previous connection is still in a timeout state.

This parameter expects a value of type Boolean.

Since:

4.1

See Also:

Socket.setReuseAddress(boolean), Constant Field Values

CONNECTION_TIMEOUT

static final String CONNECTION_TIMEOUT

Deprecated.

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

Please note this parameter can only be applied to connections that are bound to a particular local address.

This parameter expects a value of type Integer.

See Also:

Constant Field Values

STALE_CONNECTION_CHECK

static final String STALE_CONNECTION_CHECK

Deprecated.

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.

See Also:

Constant Field Values

MAX_LINE_LENGTH

static final String MAX_LINE_LENGTH

Deprecated.

Determines the maximum line length limit. If set to a positive value, any HTTP line exceeding this limit will cause an IOException. A negative or zero value will effectively disable the check.

This parameter expects a value of type Integer.

See Also:

Constant Field Values

MAX_HEADER_COUNT

static final String MAX_HEADER_COUNT

Deprecated.

Determines the maximum HTTP header count allowed. If set to a positive value, the number of HTTP headers received from the data stream exceeding this limit will cause an IOException. A negative or zero value will effectively disable the check.

This parameter expects a value of type Integer.

See Also:

Constant Field Values

MIN_CHUNK_LIMIT

static final String MIN_CHUNK_LIMIT

Deprecated.

Defines the size limit below which data chunks should be buffered in a session I/O buffer in order to minimize native method invocations on the underlying network socket. The optimal value of this parameter can be platform specific and defines a trade-off between performance of memory copy operations and that of native method invocation.

This parameter expects a value of type Integer.

Since:

4.1

See Also:

Constant Field Values

SO_KEEPALIVE

static final String SO_KEEPALIVE

Deprecated.

Defines whether or not TCP is to send automatically a keepalive probe to the peer after an interval of inactivity (no data exchanged in either direction) between this host and the peer. The purpose of this option is to detect if the peer host crashes.

This parameter expects a value of type Boolean.

Since:

4.2
