Has anyone ever seen cases where WEBrick caches pages even though it isn''t supposed to/isn''t configured to? I have an application where one of my view templates contains an <IFRAME>. This iframe has a "src" attribute that points to a file that I upload to my RoR server. Then various things happen in the app. and the file is sometimes overwritten, and then the user is redirected back to the same view, where I expect to see the updated version of the file in the iframe. In development, using WEBrick on WinXP, I will see that although the iframe page has been updated on disk, I will _not_ see the updated page in the browser. However, when I deploy the exact same code to my test environment, using Apache on Linux, I don''t see this problem - the refreshing always occurs. I''m using the same browser (same instance of the browser (different tabs) in fact) to view these different results. So I am assuming that it''s a difference in the Web servers. I have config.action_controller.perform_caching set to false in both configuration environments. Also, I''ve verified that the RAILS_ROOT/tmp/cache folder is empty on my development box.
