Constructor Detail

SpdySessionHandler

public SpdySessionHandler(SpdyVersion version,
                          boolean server)

Creates a new session handler.

Remote-initiated streams are accepted up to concurrently (matching the HTTP/2 default, see RFC 7540, Section 6.5.2). Use SpdySessionHandler(SpdyVersion, boolean, int) to configure a different limit.

Parameters:

version - the protocol version

server - true if and only if this session handler should handle the server endpoint of the connection. false if and only if this session handler should handle the client endpoint of the connection.

SpdySessionHandler

public SpdySessionHandler(SpdyVersion version,
                          boolean server,
                          int maxLocalConcurrentStreams)

Creates a new session handler.

Parameters:

version - the protocol version

server - true if and only if this session handler should handle the server endpoint of the connection. false if and only if this session handler should handle the client endpoint of the connection.

maxLocalConcurrentStreams - the maximum number of concurrent remote-initiated streams that will be accepted. This bounds the memory a remote peer can force this handler to allocate by opening streams. SYN_STREAM frames received once this limit is reached are rejected with a RST_STREAM carrying SpdyStreamStatus.REFUSED_STREAM. Must be positive.
