Hi Joel, 304 isn’t an error, it’s a server response telling the browser that he doesn’t need to load a new document, the version he already has in it’s cache still is up-to-date. What is the problem that you’re experiencing? ---

Actually we found the problem here at the office. It was a pound sign that was passed as an argument to an image\_tag that apparently was triggering another request to the server. Anyone encountered that ? Or any theoritical explanation regarding this and http or webbrick ? Joel
