Simple HTTP Requests

2. InternetOpenUrl to send a request to open a resource on a server and return a request handle

3. InternetReadFile repeatedly until all the data has been read from the server

4. InternetCloseHandle on each handle returned from steps 1 and 2

InternetOpen need only be called once, typically when the application is started or the first HTTP request is made. The handle returned by InternetOpen should eventually be closed, for example when the application terminates. ...
