The WinInet plugin for gSOAP enables client applications (not servers) to communicate through Microsoft's WinInet API on Windows. This offers all of the advantages of WinInet managed through the
Internet Options control panel of Windows, such as HTTP (proxy) authentication, TLS/SSL, and HTTP compression. Therefore, "if IE works, gSOAP works." since these options are shared by IE.
The WinInet project home is at http://code.google.com/p/gsoapwininet.
This plugin is licensed differently than the other plugins for gSOAP. It is licensed under the MIT license and can be used with GPLv2 and the commercial license for gSOAP.

In your source code for the client, register the WinInet plugin with

To control the WinInet's HttpOpenRequest options, register the WinInet plugin with
soap_register_plugin_arg() and supply an argument that is passed on to HttpOpenRequest. For example:
See the MSDN documentation on HttpOpenRequest for details of the HttpOpenRequest flags. The
wininet.h header must be included to use these flags.
INTERNET_FLAG_KEEP_CONNECTIONuse keep-alive semantics, if available, for the connection. This flag is required for Microsoft Network (MSN), NT LAN Manager (NTLM), and other types of authentication. This flag is set automatically when the soap context is initalized with
INTERNET_FLAG_IGNORE_CERT_CN_INVALIDdisables Microsoft Win32 Internet function checking of SSL/PCT- based certificates that are returned from the server against the host name given in the request.
INTERNET_FLAG_IGNORE_CERT_DATE_INVALIDdisables Win32 Internet function checking of SSL/PCT-based certificates for proper validity dates.
If there are errors in sending the HTTP request which would cause a dialog box to be displayed in IE (for instance, invalid certificates on an HTTPS connection), then a dialog will also be displayed by this library. At the moment is is not possible to disable the UI. If you wish to remove the UI then you will need to hack the source to remove the dialog box and resolve the errors programmatically, or supply the appropriate flags to
soap_register_plugin_arg() to disable the unwanted warnings.
