Web development howto?

[Jaime Barciela]

With the disclaimer that I haven't use it myself, only read *some* of
the docs, here is my (surely terrible) take at explaining the beast.

Mongrel2 is a neat idea based on 2 other projects:

 - 0mq ( http://www.zeromq.org/ ) which is an async communication
library that feels like sockets but behaves like a message queue. By
iMatix.
 - the original Mongrel http parser (
http://en.wikipedia.org/wiki/Mongrel_(web_server) ). Also by Zed Shaw.

The idea is that you have "handlers" that work on requests in an async
way. They are processes outside the web server and you can have as
many as you need anywhere in the network and can create and destroy
them as needed without disturbing the web server. This is similar to
FastCGI except you also get non-blocking I/O and a Publish/Subscribe
model for your application.

The really neat part of this is that if you look at it from the server
side looking out towards the browsers Mongrel2 essentially allows you
to include web browsers in a 0mq topology. A really nice trick.

0mq is a c library and there is a D binding for it:
https://github.com/itiu/zeromq-connector

But I haven't found a D handler for Mongrel2.


About ripping a FastCGI wrapper out of Serenity: Yes, I mean that is
actually general enough that you can make it a separate project and
use it yourself in Serenity. That would be great, not only for me but
for many newcomers like me as well.
