persistent_http

DESCRIPTION:

Persistent connections using Net::HTTP with a connection pool.

This is based on Eric Holder's Net::HTTP::Persistent libary but uses a connection pool of Net::HTTP objects instead of a connection per thread. C/T is fine if you're only using your http threads to make connections but if you use them in child threads then I suspect you will have a thread memory leak. Also, you will generally get less connection resets if the most recently used connection is always returned.

FEATURES/PROBLEMS:

  • Supports SSL
  • Thread-safe
  • Pure ruby
  • Timeout-less speed boost for 1.8 (by Aaron Patterson)

INSTALL:

gem install persistent_http

EXAMPLE USAGE:

require 'persistent_http'

class MyHTTPClient
@@persistent_http = PersistentHTTP.new(
  :name         => 'MyHTTPClient',
  :logger       => Rails.logger,
  :pool_size    => 10,
  :pool_timeout => 5,
  :warn_timeout => 0.25,
  :force_retry  => true,
  :url          => 'https://www.example.com/echo/foo'  # equivalent to :use_ssl => true, :host => 'www.example.com', :default_path => '/echo/foo'
)

def send_get_message
  response = @@persistent_http.request
  ... Handle response as you would a normal Net::HTTPResponse ...
end

def send_post_message
  request = Net::HTTP::Post.new('/perform_service')
  ... Modify request as needed ...
  response = @@persistent_http.request(request)
  ... Handle response as you would a normal Net::HTTPResponse ...
end
end
