Creating a simple Http Client using WinInet for Windows

The WinInet provides APIs to communcate (or interact) with HTTP services. I have started to use WinInet in my application (A console based one) to interact with Web Service but which leads me to write a SimpleHttp Client, which will support Http POST and Http GET requests. Although we can use WinInet directly but I have been missing the HttpClient like APIs from Apache, So i have tried to write one for me.

By the way people would love to use WinHttp Api.
