WinHTTP is a robust HTTP client component for Delphi and C++ Builder, built on top of WinInet, providing a powerful solution for managing HTTP requests.

What's more, this software supports both binary and text formats, as well as cache of Internet Explorer. Users can even resume broken downloads, and read data from password protected directories. The basic proxy authentication scheme is also supported.
Another added bonus is that WinHTTP can be used in ActiveX forms. This means users can incorporate it into web-based software installations.
Overall, I highly recommend WinHTTP. It's a reliable and easy-to-use tool with an impressive range of functions.
