trying to get a working http post working

Ok I am just starting out with winsock and have mostly done work before hand with get's only when requesting anything from a server
I am in need of information on how to post information to a website(take www.filemirrors.com for a example). I am wanting to write a program
that will allow the user to enter a name and it will post it to a webpage download the contents and display it in the program. IF anybody can
show me how please as I have no idea how to do this. Please send all suggestions if possible to my email address. I really appreciate it ahead of time

thanks and best regards,
