# GET X-, GET X+10K-, GET X+20K HTTP requests
# and we would answer these by putting megabytes
# into the stream buffer, of which only 10K would be
# used. This kills performance. Hence I add a caching
# stream that tries to resolve answers from its internal
# buffer, before reading the engine's stream.
# This works, but only if the HTTP server doesn't
# read too aggressively, i.e., uses small blocksize.
