Jozef Chuťka's Blog:
Image Caching With PHP
June 04, 2010 @ 11:33:44

Jozef Chutka was working on a Flash-based application and, in trying to optimize it, figured that he'd set up an image caching system to keep the app from having to grab the images each time. The result is shared in this post - a simple tool that relies on HTTP headers to notify the client if anything's changed.

I can not hold all of those [requests] within flash player cache because some of them may change, and I also want shortest possible respond times and client-server traffic reduction as well as server side computing reduction. That's where browser caching comes into the scene. I have experimented a bit with all possible http headers to understand each browser specifics and I came with a solution.

He includes a snippet of code that shows how it would check the current image and send the correct headers as to whether or not it needs to be updated from the cached version the application has. This also keeps you from having random parameters in your requests because the server always assures the content is fresh.
