How can I connect to internet (basically, API to connect to an HTTP

ATL doesn't have any HTTP client support. There are some HTTP client
classes in ATL Server project (which, despite the name, is completely
independent from ATL proper, but is designed in the same spirit):

I intend to use WinHttp (IWinHttpRequest). Pls let me know if there's
a better approach available possible.

There's also WinInet API and UrlMon API. Which one is better would
depend on your goals.

Also, how I can retrieve the proxy settings of "Internet Options"
(inetcpl.cpl)?

InternetQueryOption(INTERNET_OPTION_PROXY). Note that WinInet will pick
up proxy settings automatically, you don't need to do anything special.
Not sure about WinHTTP.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
