Rails: 2.3.3
Overview: I want to enable cross domain session support. Eventually,
I'll have several domains for users to choose from, i.e.
user.domain1.com or user.domain2.com. I've borrowed from the code below,
but it doesn't seem to be working.
In middleware:
class SetCookieDomain
def initialize(app, default_domain)
@app = app
@default_domain = default_domain
end
def call(env)
host = env["HTTP_HOST"].split(':').first
env["rack.session.options"][:domain] = custom_domain?(host) ?
".#{host}" : "#...@default_domain}"
@app.call(env)
end
def custom_domain?(host)
domain = @default_domain.sub(/^\./, '')
host !~ Regexp.new("#{domain}$", Regexp::IGNORECASE)
end
end
In environment.rb:
config.load_paths += %W(#{RAILS_ROOT}/app/middlewares)
In development.rb:
config.middleware.use "SetCookieDomain", ".mydomain.com"
