"yum update" failed behind corporate proxy

Hi, I have F7 installed and when I connect to Internet using ADSL
connection,
"yum update" works.

but when I connected inside corporate network, it must go through proxy.

I tried many ways to set proxy, all failed.

my proxy need username and passwd, and in my username, there is a
"space" and "-", is this causing problem?

Thanks,
Houxiang
