A rather simple question. Should I use the WinHttp library to make a web service request in my C++ programs or should I use the IXmlHttpRequest interface in the msxml library to send web service requests? Obviously the WinHttp library provides a lot more fine control compared to the IXmlHttpRequest library. But the XmlHttpRequest object is a w3.org standard and in theory more portable.

    It depends whether you are accessing the service on secure channel i.e. HTTPS or simple one i.e. HTTP.

    As per MSDN (http://msdn.microsoft.com/en-us/library/ms891732.aspx), IXMLHttpRequest supports only HTTP.

    Note IXMLHTTPRequest does not support secure website access. To access a secure website, use the WinINet API.

    But WinInet API is quite old and have some multi-threading issues (I think its there on MSDN too)…

    So the best bet is WinHTTP for HTTPS and HTTP, otherwise good old IXMLHttpRequest.

    Note: libcurl and curlpp (c++ port of libcurl) is also there to check. There is an old post for this http://stackoverflow.com/questions/1011339/how-do-you-make-a-http-request-with-c
