How to set proxy authentication when installing?

tornader

Hello everyone! I am a university student and I can't visit the web server outside of China. So ,I use proxy to install OpenBSD(the proxy need for authentication). When I get into the step bellow, I do not know how to set proxy authentication correctly. I tried for times, but failed.

Let's install the sets! Location of sets? (cd disk ftp http or 'done') [cd] ftp
HTTP/FTP proxy URL? (e.g. 'http://proxy:8080', or 'none') [none]

Supposing my proxy server use http protocol, and its IP address is *.*.0.9, and the username is abc.s34(please notice that it has a dot inside), the password is abc. So, what should I input for HTTP/FTP proxy URL?

Thank you!
