That URL pattern doesn't point to an actual physical filesystem location. That said, I don't know if there's a file being written somewhere or not. > Now to throw another monkey wrench into the whole schema.... > How effective is this within a Load Balancing configuration? > Is the image generated on SERVER A and then the request is > moved to SERVER B for the remaining requests (all one single > web transaction), and then the image is no longer viewable > since the end user is now on SERVER B but the image is on SERVER A? Whether it creates an image in memory or on the filesystem, it won't work in a fully load-balanced environment. The user will have to view the image on the server that generated it. If you're using sticky sessions on your load balancer, it'll work.
