Hi Jeroen!

Sorry about the late response, it was the long weekend here in the
Philippines and I took some time off to have fun with the family. See
some of my thoughts below. :)

Thanks, it has been in the back of my mind for a while and I think
there's no better way to address it than to actually do something
about it.

Ah, yes. The rationale is really simple:

1. I'd like it done test-driven, meaning actual requirements dictate
the implementation. This is hard to do if you're going to be basing
the implementation on something already existing. At least this is my
personal view on it.

2. The license might be an issue if I base the implementation on
something existing. Given that cpp-netlib is licensed under the Boost
Software License, anything that is licensed under a non-BSL compatible
license is a non-starter.

3. I'd like to gain more experience writing more parsers by hand to
get a better understanding and get a better chance at optimizing the
implementation at any given point in the future. ;)

So if you can suggest anything that is already Boost Software Licensed
that I can just tweak -- something like what is already in Boost.Asio
examples, which BTW, we already use in the HTTP Server implementation
-- then it might be something I'd be willing to look into. :D

Yes, thanks. I however would like to deal with the RFC issues later,
just as soon as I can parse a valid narrow subset of the RFC. My aim
is really to get something that will allow me to just parse the "known
good" incoming data in an incremental manner. I will however base test
inputs on the RFC, so that might allow me to go RFC-compliant in the
tests, while the implementation might be narrower than the full RFC
implementation.

No worries -- I'm looking forward to construe_cast be proposed and
included in Boost myself ;). I will try to post more about the
progress and discoveries I make along the way.

Thanks Jeroen and I definitely look forward to more of your insights
as I continue working on this particular part of the library! :)
