WinHTTP

The WinHTTP Delphi component is an easy to use WinInet-based HTTP client component that will allow you to post and get any data from the Web via HTTP protocol. With WinHTTP you can grab Web pages, download files and documents (or only their headers without the content), get results of the CGI programs (for example, results of web-based search engines / databases), or even upload files to the CGI programs.
In case if you want download documents from local intranet - just specify file:// prefix in the URL instead of http://. The WinHTTP can download web content both in binary and text formats, supports cache of Internet Explorer, can resume broken downloads, read data from password protected directories and supports basic proxy authentication scheme. Also it can be used in ActiveX forms, for example to build Web-based installations.
Requirements:
· Delphi 2/3/4/5/6/7/2005/2006/2007, C++ Builder 3/4/5/6/2006
Limitations:
· You can try it out for free, but if you like it and want to use it you have to register it with the author.
· The only difference between the unregistered and registered versions is that
the registered one has not message box with remind to register and works without Delphi (C++ Builder) running. You can also purchase the source code, if you would like to have it, and be able to compile or modify the AutoUpgrader on any 32bit version of Delphi or C++ Builder.
