I should have mentioned that I reset the websockets buffer after reading from the deflater. A small self-contained example with this code would be tricky with all of the websocket handling stuff in the way. Regardless, with permessage-deflate, the sliding window must be maintained across messages unless no_context_takeover is being used. Creating a new deflater for each message doesn't work. I'm not entirely clear with how to work with Reset, specifically the use of dictionaries. Passing 'nil' as a dictionary hasn't gotten me anywhere. I'm guessing that might be the key detail for maintaining the sliding window?
