= fcgi - The New generation of FastCGI library for Ruby.

Version 0.9.2.1

== Depends

=== C version
  * ((<libfcgi|URL:http://www.fastcgi.com/#TheDevKit>))(FastCGI Developer's Kit)

=== Pure Ruby Version
  * StringIO

== Install

  $ gem install fcgi

== Usage
=== Class Method
--- FCGI.accept
    Returns FCGI instance
--- FCGI.each

--- FCGI.each_request

--- FCGI.is_cgi?

--- FCGI.each_cgi
    Automatically detects whether this program is running under the FastCGI
    environment, and generates a 'CGI' type object for each request. Also
    installs signal handlers for graceful handling of SIGPIPE (which may
    occur if a client gives up on a request before it is complete) and
    SIGUSR1 (generated by Apache for a 'graceful' exit)

    If you are using the HTML output methods you can also pass the HTML type
    e.g. FCGI.each_cgi('html3') do ... end

    However, you should beware that the CGI library is quite slow when
    used in this way, as it dynamically adds a large number of methods
    to itself each time a new instance is created.

=== Instance Method
--- FCGI#finish
    Finish

--- FCGI#in
    Returns Stream or StringIO

--- FCGI#out
    Returns Stream or StringIO

--- FCGI#err
    Returns Stream or StringIO

--- FCGI#env
    Returns Environment(Hash)

== Sample

Using the FastCGI native interface:

  #!/usr/bin/ruby
  require "fcgi"

  FCGI.each {|request|
    out = request.out
    out.print "Content-Type: text/plain\r\n"
    out.print "\r\n"
    out.print Time.now.to_s
    request.finish
  }

Using the CGI-compatible interface, which works both as a standalone CGI
and under FastCGI with no modifications:

  #!/usr/bin/ruby
  require "fcgi"

  FCGI.each_cgi {|cgi|
    name = cgi['name'][0]
    puts cgi.header
    puts "You are #{name} " if name
    puts "Connecting from #{cgi.remote_addr}"
  }

Note: you can't reference CGI environment variables using ENV when under
FastCGI. It is recommended that you use the CGI-generated methods, e.g.
cgi.remote_addr as above.

If you need to access environment variables directly, perhaps extra ones set
in your Apache config, then use cgi.env_table['REMOTE_ADDR'] instead. This
isn't quite as portable because env_table is a private method in the
standard CGI library.
