Or user space buffers. You would not want to parse the requests by using
read(fd, buf, 1).

It is that easy. For a proxy call it de-pipeline-isation. In a proxy
this behaviour would destroy the benefit of pipelining. But not the data.
The hard part is writing the proxy so that it still pipelines the
requests to the server. There you get the increased complexity for
security and bandwith limiting. But that is not required for HTTP/1.1
conformance and an actually working setup.
