a couple of questions for me to grasp the concept:
should i set expire headers for images to far future even if i might be edit them (optimize, resize or whatever) next week?
what about css files? i usually have to change something in those, probably more likely than the images.
what’s about ‘the filename has to be changed every time u edit them’?
otherwise the cached image will show instead?
kinda sucks to change the filename inside code all the time if they’re used in a lot of places, no?
