Control arduino outputs on a web page with an arduino? Answered

So what I'm trying to do is control, let's say and LED, that's on output 13 on my arduino over a web page from anywhere in the world. I have an arduino uno R3 and an Ethernet shield. I've looked for tutorials but I'm really new and I'm not good at adapting other peoples code for my use, so does anyone have a simple sketch I can use to turn on an LED from a webpage?
