Patrick, in an earlier thread regarding removal of implicit C-E gzip, you wrote [1] ...

"CE gzip was made a fixed part of the protocol, in part, because intercepting intermediaries (or antivirus libraries as a subset of that) were explicitly stripping negotiation for it for their own convenience. Making it non negotiable enhances the robustness of the protocol against that which is imo the right trade given the history here and the importance of compression."

In light of the mounting support against implicit C-E gzip, how would you propose to deal with the problem you mentioned above? and the importance of compression?



As Matthew pointed out, if a server wants the ability to always use compression, no matter what, then the only place that will likely be possible is at the transport/framing layer. Other ideas? Or is compression not that important that you would be willing to use it?



I bring it up because making transport/framing gzip optional, means that servers won't always have the option to compress.
