Class Overview

Defines parameter names for connections in HttpCore.

Summary

Constants
String CONNECTION_TIMEOUT Determines the timeout in milliseconds until a connection is established.
String MAX_HEADER_COUNT Determines the maximum HTTP header count allowed.
String MAX_LINE_LENGTH Determines the maximum line length limit.
String MIN_CHUNK_LIMIT 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.
String SOCKET_BUFFER_SIZE Determines the size of the internal socket buffer used to buffer data while receiving / transmitting HTTP messages.
String SO_LINGER Sets SO_LINGER with the specified linger time in seconds.
String SO_REUSEADDR Defines whether the socket can be bound even though a previous connection is still in a timeout state.
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).
String STALE_CONNECTION_CHECK Determines whether stale connection check is to be used.
String TCP_NODELAY Determines whether Nagle's algorithm is to be used.

Constants

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.

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.

Constant Value: "http.connection.timeout"

public static final String MAX_HEADER_COUNT

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.

Constant Value: "http.connection.max-header-count"

public static final String MAX_LINE_LENGTH

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.

Constant Value: "http.connection.max-line-length"

public static final String MIN_CHUNK_LIMIT

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.

Constant Value: "http.connection.min-chunk-limit"

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.

Constant Value: "http.socket.buffer-size"

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.

Constant Value: "http.socket.linger"

public static final String SO_REUSEADDR

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.

See Also
Constant Value: "http.socket.reuseaddr"

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
Constant Value: "http.socket.timeout"

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 Value: "http.connection.stalecheck"

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.

Constant Value: "http.tcp.nodelay"
