<h1>Sinatra::Cookies</h1>
<p>Easy way to deal with cookies</p>
<h2>Usage</h2>
<p>Allows you to read cookies:</p>
<pre>get '/' do
"value: #{cookies[:something]}"
end</pre>
<p>And of course to write cookies:</p>
<pre>get '/set' do
cookies[:something] = 'foobar'
redirect to('/')
end</pre>
<p>And generally behaves like a hash:</p>
<pre>get '/demo' do
cookies.merge! 'foo' => 'bar', 'bar' => 'baz'
cookies.keep_if { |key, value| key.start_with? 'b' }
foo, bar = cookies.values_at 'foo', 'bar'
"size: #{cookies.length}"
end</pre>
<h3>Classic Application</h3>
<p>In a classic application simply require the helpers, and start using them:</p>
<pre>require "sinatra"
require "sinatra/cookies"
# The rest of your classic application code goes here...</pre>
<h3>Modular Application</h3>
<p>In a modular application you need to require the helpers, and then tell the
application to use them:</p>
<pre>require "sinatra/base"
require "sinatra/cookies"
class MyApp < Sinatra::Base
helpers Sinatra::Cookies
# The rest of your modular application code goes here...
end</pre>
