This examples and the tutor 5 lesson will introduce you to Internet and Indy Sockets and the library in a separate way. So what are the Indy Sockets and the TelnetTCPSocketServer TTSS? Indy.Sockets (VCL) is an open source socket library that supports clients, servers, TCP, UDP, raw sockets, as well as over 100 higher level protocols such as SMTP, POP3, FTP, HTTP, and many more. Indy.Sockets is written in Delphi but is available for C#, C++, Delphi any .net language, and Kylix (CLX) too. In our case we show two examples of HTTP (and a third one at your own service). Let’s begin with HTTP (Hypertext Transfer Protocol) and TCP. TCP/IP stands for Transmission Control Protocol and Internet Protocol. TCP/IP can mean many things, but in most cases, it refers to the network protocol itself.
