It's not too hard. Like Dar said, get a good HTTP book, or do some 
searching on Google. Basic HTTP requests are not complex. The request 
methods commonly used are GET, HEAD, and POST. A request is a single 
line followed by a double newline. Additional headers can be added one 
per line, before the double newline. Use a terminal and a telnet 
program to experiment. Here I am using the HEAD command to get info 
about an image on runrev.com's webserver. Use GET to download stuff.
