Description
INetAll sample is a client application that can download files using FTP, HTTP, or FILE protocols. It implements FTP and HTTP URL access using Wininet functions, and FILE URL access using Win32 CopyFile API
More Details
This sample uses InternetOpenUrl, InternetReadFile to do FTP and HTTP access. When accessing a FTP server with direct Internet access or a TIS proxy server, it also uses the INTERNET_FLAG_RAW_DATA flag in InternetOpenUrl and InternetFindNextFile to enumerate the directories and files on the FTP server. When a CERN proxy is used to do FTP, the proxy server uses FTP protocol to communication with the FTP server, and HTTP Protocol with the client. You can not use INTERNET_FLAG_RAW_DATA with a CERN proxy server.
