variables http_proxy in current 9 and 7.3-rc2

[Sylvio César]

Hi,

     I have tree VM, (8.0, 7.3RC2, 9-current), in release 8.0 I have
not problem with variables: HTTP_PROXY, http_proxy, but in 7.3 and
9-current, seems that the part of authentication is not exported.
     I use shell tcsh, my variables:
        setenv HTTP_PROXY http://user:pass@proxyserver.com:80
        setenv http_proxy http://user:pass@proxyserver.com:80

This configuration is ok in 8.0, but in 7.3RC2 and 9 I get: "Proxy
Authentication Required"

Somebody have this problem?
