library written in Object Pascal
, an object-oriented version of Pascal. It includes clients, servers, TCP, UDP, and raw sockets, as well as over 100 higher level protocols implementations such as SMTP, POP3, NNTP, and HTTP. Indy includes support for OpenSSL
and Zlib
in the protocol implementations. Indy 10 was ported to Free Pascal
, and runs on Windows
, FreeBSD
, Linux
, and Darwin
.
Internet Direct is available for Borland Delphi
, C++ Builder
, and Kylix
. The software is dual-licensed under the "Indy Modified BSD License" and the "Indy MPL License". As of early 2008, there is a new project called Indy#, which intends to write a C# version from the ground up.
Kudzu) in 1993 in Visual Basic. In 1995, he ported it to Borland Delphi and deprecated the Visual Basic version. In 1997, he made it available under an open-source license. In 2000, Winshoes was renamed to Internet Direct (Indy for short) and became cross-platform. In 2001, Borland began including it as a part of Borland Delphi, C++ Builder, and Kylix. In 2003, Indy was ported to Delphi for .NET. The following year, Indy was made available to the Microsoft .NET
community.
