Tiago Dionizio's lzlib?

Yes, that one; sorry.
If yes, here is an usage example:

           local ok, zlib = pcall( require, 'zlib' )

           if ok and zlib then
               local aContent = tostring( aResponse.content )
               local zContent = zlib.compress( aContent, 9, nil, 15 + 16 )

               if zContent:len() < aContent:len() then
                   aResponse.header[ 'content-encoding' ] = 'gzip'
                   aResponse.header[ 'etag' ] = nil
                   aResponse.content = zContent

Right, I had no problem trying out compress() and uncompress() (although the options are still kinda mysterious).

What I'm trying to understand is how to process in a stream, from a source to a sink without necessarily holding the entire message body in a buffer; the userdata returned by compressobj() and decompressobj() seem to be what I'm after but so far I don't quite grok them.

Thanks for your help.
