Example 8 with Http2Frame

use of com.webpieces.http2parser.api.dto.lib.Http2Frame in project webpieces by deanhiller.

the class TestS4FrameSizeAndHeaders method testSection4_3InterleavedFrames.

/**
	 * Each header block is processed as a discrete unit. Header blocks 
	 * MUST be transmitted as a contiguous sequence of frames, with no interleaved 
	 * frames of any other type or from any other stream. The last frame in a 
	 * sequence of HEADERS or CONTINUATION frames has the END_HEADERS flag set. The 
	 * last frame in a sequence of PUSH_PROMISE or CONTINUATION frames has the 
	 * END_HEADERS flag set. This allows a header block to be logically equivalent to a single frame.
	 * 
	 * Header block fragments can only be sent as the payload of HEADERS, PUSH_PROMISE, or 
	 * CONTINUATION frames because these frames carry data that can modify the 
	 * compression context maintained by a receiver. An endpoint receiving 
	 * HEADERS, PUSH_PROMISE, or CONTINUATION frames needs to reassemble header 
	 * blocks and perform decompression even if the frames are to be discarded. A receiver 
	 * MUST terminate the connection with a connection error (Section 5.4.1) of 
	 * type COMPRESSION_ERROR if it does not decompress a header block.
