I should probably know this, what with all the tutorials I've read, and the little things I've programmed, but I don't.

I'm making a program that will find and save a URL, but I don't know how to get it to recognize the entire URL. Basically, I can get it to find the "http://" and the ".com" but I don't know how to tell it to accept what's in the middle.

I'm guessing someone out there knows how?
