I have a Rails 2.3 application with about 45,000 active users. We currently store sessions in the database with active_record_store. I recently tested switching the session store to memcache, but within a day of it running, we had a few users write in saying that they logged in and saw other users'' data. I switched back to active record, no more complaints. That reminded me that when I had tried this a year or so ago, I''d seen a similar problem. Does anyone have any idea why that might be happening? Here''s the section I was using in config/environments/production.rb require ''memcache'' memcache_options = { :compression => true, :debug => false, :namespace => :myapp, :readonly => false, :urlencode => false } CACHE = MemCache.new memcache_options CACHE.servers = ''localhost:11211'' ActionController::Base.session_options[:cache] = CACHE config.action_controller.session_store = :mem_cache_store -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
