user and password proxy

[Julian Bolivar]

Hello every body,

I'm trying to download packages and ports from openBSD's mirrors but I 
need to pass by a proxy, I defined the http_proxy and ftp_proxy in ksh

export http_proxy=http://proxy:port
export ftp_proxy=ftp://proxy:port

and it work fine, but when I try to use a user-password proxy I defined 
the variables:

export http_proxy=http://user:[EMAIL PROTECTED]:port
export ftp_proxy=ftp://user:[EMAIL PROTECTED]:port

but it din't work,  any one know how I can define the proxy's user and 
password?

Thanks and Regards,

Julian Bolivar
