what's the widespread use of ECN? or SACK when that was first put in?
what about ipchains before 2.2 was released?

why bother being the first to implement anything new, might as well wait
for the commercial folks to put it into a product and spread it wide and
far eh?

i'm pretty sure i said that it was our (the apache group's) position that
we wanted as perfect as possible of a pipelining implementation so that
should someone finally do a client-side version then there wouldn't be
apache bottlenecks in the way. i still think that's the right attitude.
if we'd left the packet boundaries in there then there wouldn't even be
motivation to bother doing a client-side pipelining implementation,
there'd be little or no benefit.

btw, HTTP/1.1 proxying is more challenging than HTTP/1.0 proxying which is
probably why squid doesn't support it yet (nor does the apache proxy
module).
