How to send http post with socket connection

Question

I want to send HTTP POST command to a server with socket connection.

How can I do it with indy?

By the way, what is HTTP? and what is Socket? Is IdHTTP a socket?

I've already googled but not found the things that i want to know. — Cậu Bé Chăn Bò, Jul 23 '13 at 20:38
This is a lot of questions rolled up into one, which makes it difficult for people to answer. Do some research on the terms you're curious about, and come back with specific parts you don't understand. — thumbtackthief, Jul 23 '13 at 20:46

HTTP is an application-layer protocol that runs on top of TCP/IP. You create a TCP/IP socket an connect it to the desired server, then exchange HTTP messages back and forth as needed. Indy's `TIdHTTP` handles all of those details for you. All you have to do is tell it where to connect and what to send. — Remy Lebeau, Jul 23 '13 at 21:16

IdHTTP is not a socket, it´s a VCL component that implements a HTTP client. It´s indeed used to send HTTP commands to a web server, like the POST you want to perform.

Http: http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol

Socket: http://en.wikipedia.org/wiki/Network_socket
