The 304 Not Modified processing message is occurring with every JavaScript (.js) file type in the assets folder of the project, on the localhost. The experienced problem is a slow loading time of the web pages.
Is there anything specific with Webrick and the JavaScript (.js) file types in combination, which causes this to happen?
Notice: Webrick is used with Ruby on Rails 3.2 and jQuery UI
