Solution 2 - Ruby on-Rails
Reading the discussion based on tehgeekmeisters answer, this warning is popping up as Rails is using Rack cookies in a different way than intended. It should be ok to just ignore this warning for now until there is a final agreement on how to handle this issue and a fix in place.

rails 3.2.9 - ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]
Hello everyone, the following has worked for me, it may work for you.
/usr/local/lib/ruby/gems/1.9.1/gems/actionpack-3.2.9/lib/action_dispatch/middleware/session/abstract_store.rb
module Compatibility
def initialize(app, options = {})
options[:key] ||= '_session_id'
#fixed warning - SECURITY WARNING: No secret option provided to Rack::Session::Cookie.
options[:secret] ||= Rails.application.config.secret_token
super
end
end
Solution 5 - Ruby on-Rails
Downgrading to rack 1.4.1 should be sufficient to solve this for now. There's an issue open for this and I just submitted a pull request that seems to fix it for me. In any case, watch the issue, and you should be able to upgrade to rack 1.4.2 after this is fixed.
Apparently, there's ongoing discussion about how to fix this on another issue. You'll have to either downgrade to 1.4.1, ignore it, or figure out your own fix until this is dealt with (and backported, if that even happens).
Solution 6 - Ruby on-Rails
An issue has been opened in Github https://github.com/rails/rails/issues/8789. It appears that a bug involving Rails 3.2.10 with Rack 1.4.2 is causing this. IMO, it can be safely ignored till the issue is resolved.
EDIT: This issue has been resolved in Rails 3.2.11.
Solution 7 - Ruby on-Rails
rails update to 3.2.13 ,can solve this question.
