Zbatery is an HTTP server for Rack applications on systems that either  
do not support fork(), or have no memory (nor need) to run the  
master/worker model. It is based on Rainbows! (which is based on  
Unicorn (which is based on Mongrel)) and inherits parts of each.  
Zbatery supports your choice of all the thread/fiber/event/actor-based  
concurrency models and Rack middleware that Rainbows! supports (or will  
ever support) in a single process.

Zbatery will still exploit certain features of Unix for transparent  
upgrades, log reopening, and graceful stops, but does not rely on them  
for basic functionality.

== Features

- Designed for {Rack}[[http://rack.rubyforge.org/](http://rack.rubyforge.org/)], the standard for  
modern Ruby HTTP applications.

- Configuration files are compatible with Rainbows!, a superset  
of the Unicorn  
{DSL}[[class Unicorn::Configurator](http://unicorn.bogomips.org/Unicorn/Configurator.html)].

- Inherits all features and concurrency models Rainbows! supports  
(and ever will support): [http://rainbows.rubyforge.org/Summary.html](http://rainbows.rubyforge.org/Summary.html)

- -Untested- Works under operating systems that don’t support signals,  
pipe and fork(). Unicorn 0.95.2+ has rake-compiler support, so  
compiling the HTTP parser should be easier at least.

- -Untested- HTML 5 Web Sockets support
