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 ...
