	 * 
	 * 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.
