Sessions:

To save data across multiple requests, you can use either the session or the flash hashes. A flash stores a value (normally text) until the next request, while a session stores data during the complete session.

session[:user] = @user flash[:message] = "Data was saved successfully" <%= link_to "login", :action => 'login' unless session[:user] %> <% if flash[:message] %>

<% end %>

It's possible to turn off session management:

session :off # turn session management off session :off, :only => :action # only for this :action session :off, :except => :action # except for this action session :only => :foo, # only for :foo when doing HTTPS

       :session_secure => true 

session :off, :only=>:foo, # off for foo,if uses as Web Service

       :if => Proc.new { |req| req.parameters[:ws] }

Following is the syntax for setting cookies:

1. Set a simple session cookie

cookies[:user_name] = "david"

1. Set a cookie that expires in 1 hour

cookies[:login] = { :value => "XJ12", :expires => Time.now + 3600}

Following is the syntax for reading cookies:

cookies[:user_name] # => "david" cookies.size # => 2

Following is the syntax for deleting cookies:

cookies.delete :user_name

All the option symbols for setting cookies are:

   * value - the cookie.s value or list of values (as an array).
   * path - the path for which this cookie applies. Defaults to the root of the application.
   * domain - the domain for which this cookie applies.
   * expires - the time at which this cookie expires, as a +Time+ object.
   * secure - whether this cookie is a secure cookie or not (default to false). Secure cookies are only transmitted to HTTPS servers.
