Re: Parsing http within squid

Well, the important bit to realise is that there's no guaranteed
"entire message" anywhere inside Squid core for the request and reply
body. The icap code may do something to buffer the POST but it could
get big.

For small-scale loads you can get away with just buffering the whole
thing until you've got enough to parse. For larger loads you don't
have this luxury and have to try and heal incremental parsing.
