I have filed an issue and mentioned on several occasions that I would like a setting (that can be passed in the initial HTTP/2 setup) to disable Huffman, just as we have a setting for the header table size. > > I don't think that would be overwhelming to test or implement, and since we are already asking implementations to track header representations that must be preserved (literal headers without indexing) I don't think it would be stretch to have a way to say "do not Huffman compress at all". On this topic, has there been any consideration given to a potential need to alter the huffman code table after release? Perhaps after real world deployment someone determines that slightly different weighting would lead to improved packet size. My apologies if this was discussed in a past thread. -- Jason T.
