Rack::NonCache

Rack::NonCache is a rack middleware that disables HTTP browser caching.

Installation

From Gem:

$ sudo gem install rack-noncache

With a local working copy:

$ git clone git://github.com/dsaenztagarro/rack-noncache.git
$ rake package && sudo rake install

Basic Usage

Rack::NonCache is implemented as a piece of Rack middleware and can be used with any Rack-based application. If your application includes a rackup (.ru) file or uses Rack::Builder to construct the application pipeline, simply require and use as follows:

require 'rack/noncache'

use Rack::NonCache,
    :whitelist => ['/path/to/non/caching/url', ...,
                   Regexp.new(/^\/path\/to\/non\/caching\/url/)]

run app

Assuming you've designed your backend application to take advantage of HTTP's caching features, no further code or configuration is required for basic caching.

Using with Rails

Add this to your config/environment.rb:

# White list approach (option 1)
config.middleware.use Rack::NonCache,
    :whitelist => ['/path/to/non/caching/url', ...,
                   Regexp.new(/^\/path\/to\/non\/caching\/url/)]

# Black list approach (option 2)

config.middleware.use Rack::NonCache,
    :blacklist => ['/path/to/non/caching/url', ...,
                   Regexp.new(/^\/path\/to\/non\/caching\/url/)],

You should now see Rack::NonCache listed in the middleware pipeline: rake middleware
