A free component performing HTTP requests and examine HTTP responses .
EditByBSEditor: The Coalesys HTTP Client is a free component which was created to address the needs of developers who wish to perform HTTP requests and examine HTTP responses using a simple, high performance COM object.

Implemented as an ActiveX DLL, the Coalesys HTTP Client was written entirely in Visual C++ and is dependency-free, not requiring any MFC, ATL or WinInet DLLs. It leverages the same technology found in the Coalesys Winsock Library.

With the Coalesys HTTP Client you can:

Use any valid HTTP Request method (GET, HEAD, POST, etc.).

Connect to a server on any port.

Customize Request headers.

Configure for use of a proxy server.

Retrieve Response Status, Headers and Body as strings.
Use in any compatible ActiveX environment, including those that do not support events (such as ASP).

NEW:
Added a new COM object that natively supports Microsoft Windows
x64 Editions (note, this object needs to be manually registered
with the operating system to be utilized). you can free download HTTP Client Library 1.0 Build 93 now.
