If you access the Internet behind a firewall, the connection’s proxy options must be set.
Set the proxy options for HTTPS protocol as seen below:
iRetVal = InternetSetOptionStr(hHttpOpenRequest, _ INTERNET_OPTION_PROXY_USERNAME, _ username, Len(username) + 1)
iRetVal = InternetSetOptionStr(hHttpOpenRequest, _ INTERNET_OPTION_PROXY_PASSWORD, _ password, Len(password) + 1) |
Note: Proxy authentication only works for IE4.0 wininet. For IE3.0x, you will need to manually add the Proxy Authentication header.
