Example 10 with Http2Frame

use of com.webpieces.http2.api.dto.lowlevel.lib.Http2Frame in project webpieces by deanhiller.

the class TestC4FrameSizeAndHeaders 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.
