That got me to thinking about how AOLserver works on responses -

So a single thread handles the receiving of the request - which makes
perfect sense on requests < around 32K or so, which is probably 99.5% of them.

What about on output? In other words, a request comes in, the single IO
thread reads it, then once its finished it gets handed out to a thread for
processing. What happens when its done? Does that thread do all the output
on its own? In my imaginary world, I would love it if the thread handed the
output data back to the central I/O thread, which could return it to the
client at its own pace. AOLserver's I/O thread would get huge in terms of
memory for doing this, but it _should_ act as a powerful connection
multiplexor - you can imagine possibly 2x maxthreads connecting, and if the
individual threads finished off the connections quickly, returning data to
the central thread - well, it would pretty much obviate the need for caching
proxy servers in front of AOLserver, right?

If it already works this way - then architectural bits like that should be
showcased so that more users choose AOLserver. If it doesn't - does what I
say make sense? Would it have too much memory impact?

Sorry for the ramble, your previous response and that URL got me to thinking
about an idea I had had before...
