I''m building a session-less application and have set "session :off" in the base controller (ApplicationController in application.rb). Unfortunately, I still see session files appearing in /tmp/ruby_sess.* -- and the cause of these files is when a routing error occurs. Whenever a bad URL comes in, for example <http://localhost:3000/not/a/chance/in/hell>, the RoutingError exception is raised then the session file is created. I see this behavior in both the development (WEBrick) and production (Apache) environments. After reading <http://wiki.rubyonrails.org/rails/pages/HowtoChangeSessionOptions>, I tried this as a workaround in environment.rb: ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update(:disabled => true) That didn''t help. It appears that this problem occurs after the render_* methods, while ActionController is building the response, so I''m not sure how to workaround it. FYI, I found this problem because of a bad image URL that someone had entered into a database. I don''t want to solve this problem by doing URL validation :-) Any help or suggestions would be most appreciated. -ch -- Posted via http://www.ruby-forum.com/.
