Issue in delete a cookie ( cannot 'eat' it.)

I set my cookies at root domain level ( lvh.me in dev) , accessible
from
within each subdomain
w session store initializer :
Rails.application.config.session_store :active_record_store, :key =>
‘_tests_session’, :domain => :all
( good for persisted facebook authentication when user login into a
different subdomain)

when a user login into a subdomain, I have
cookies[:login]
“{:user_id=>3, :subdomain_name=>“coocoo”}”

when the user logout , I should delete this cookie,
cookies.delete(:login, :host => Rails.configuration.host) if
cookies[:login]

but it doesn’t delete it … any clue ?
thanks for feedback

Did you try setting your domain to the actual domain?

Rails.application.config.session_store :active_record_store, :key =>
‘_tests_session’, :domain => ‘example.com

when a user login into a subdomain, I have
cookies[:login]
“{:user_id=>3, :subdomain_name=>“coocoo”}”

when the user logout , I should delete this cookie,
cookies.delete(:login, :host => Rails.configuration.host) if cookies[:login]

It’s not useful in my case , as I am using FB & Google
authentification,
the callback can be set only to the main domain
using the :state parameter I can redirect to the calling subdomain on
FB/Google callback
but before the redirect I need to delete the previous session/cookies (
user may have been logged in an another subdomain or root domain)

setting :domain => :all , means that the cookies :host is/should_be
‘.example.com’
and I should be able to delete it : ( as per Rails API)

cookies.delete(:login, :host => ‘.example.com’) but it’s not working

I am going to test another way : expiring the cookie,…

def remove_all_cookies(domain=nil)
unless domain.nil?
cookies.to_hash.each_pair { |k, v| cookies[k.to_sym] = { :value
=>
‘’, :path => ‘/’, :domain => domain, :expire => 1.day.ago } }
end
end

[SOLVED] the issue was not with cookies … I had to change the way I
handle the session store w subdomain … should not using domain =>
:all

I finally set in initializers/session_store.rb

Rails.application.config.session_store :active_record_store, :key =>
‘_myapp_session’, :domain => {
production: ‘myapp.com’,
development: ‘lvh.me’}.fetch(Rails.env.to_param.to_sym, :all)

so now I can set/delete the cookies[:login] according to user
authentication w FB/Google and originated subdomain ( parameter :state
in
URL)

on signout, I have to delete the cookies[:login], on redirection I have
to
check if the cookies[:login] is related to the subdomain else delete
it…

great post and link about it :

Quoted- As it turns outs ‘domain: all’ creates a cookie for all the
different subdomains that are visited during that session (and it
ensures
that they are passed around between request).
If no domain argument is passed, it means that a new cookie is created
for
every different domain that is visited in the same session and the old
one
gets discarded.
What I needed was a single cookie that is persistent throughout the
session, even when the domain changes. Hence, passing ‘domain: lvh.me
solved the problem in development. This creates a single cookie that
stays
there between different subdomains.
