i’m running ruby on webrick and it causes strange problems: sometimes the images doesn’t appear and only when i refresh they appear again. the css doesn’t load at all (tested on chrome) but ,somehow, when i tested in on firefox , it was loaded only after clearing the cache i’m using ruby 1.87 with rails 2.3.5 on linux machine thanks ---

View the page source in your browser and copy/paste the full html text into the w3c html validator (use google to find it). Alternatively (or also) install the html validator plugin to firefox that checks the html as you develop it. Colin ---
