I have an app that serves web image assets from both locations. I have watched the two railscasts on this topic but what are the REAL advantages of serving images this way. I see the timestamp on the file; does this cause problems with working with a CDN like cloudfront? Or a reverse proxy such as Varnish? Are there any performance metrics for serving from /public vs /app/assets using Nginx?
In short, I understand advantages of CSS and Javascript but am not sure if it justifies moving the images from /public to /app/assets. What is the most compelling reason to do so? And are there any significant downsides esp as it relates to a CDN?
thx
