Overview

A FastCGI adaptor for Wee.

Depends on ruby-fcgi (raa.ruby-lang.org/list.rhtml?name=fcgi) or via Rubygems (gem install fcgi).

Example of usage:

require 'wee/adaptors/fastcgi'
Wee::FastCGIAdaptor.start('/app', application)

Setup FastCGI with Lighttpd

# lighttpd.conf
server.modules = (
"mod_fastcgi"
)

fastcgi.server = (
"/app" =>
  ( "fcgi" =>
    (
      "host" => 127.0.0.1",
      "port" => 3000,
      "check-local" => "disable"
    )
  )
)

Now start the Wee application (the file must be executable):

spawn-fcgi -f ./run.rb -p 3000

Finally start the lighttpd server:

lighttpd -D -f lighttpd.conf
