Look. Here’s the deal, fuckbrains. I’m tired of answering all your fucking shit. Send me an If-Modified-Since or If-None-Match, and if your shit doesn’t need to be sent, I’m not going to fucking waste my damn time fucking over a database and some shitty telephone line to send you a few dozen bytes of data if it’s no different than what I’ve fucking told you already. You fucking dipshit, didn’t you listen to me the first time? No talent assclown...
