Http proxy not passing Auth request Basic header

[smarx80]

Hi,
I've configured WordPress to use an HTTP Proxy, using
WP_PROXY_* consts in wp-config.php

All outgoing communications are passed to the proxy, but we have an authentication problem.

It seems that, using libCurl transport, in curl_before_send are set only

CURLOPT_PROXYAUTH e CURLOPT_PROXYUSERPWD

but not "Proxy-Authorization: Basic" header.

Just for test, I've disabled curl transport ( in Request/Transport/cURL.php - function test() I've done a shortcircuit to false ), so using fsockopen
I can authenticate regularly.

Maybe there is an implementation bug?

Have you a solution for this or some test to run to help you?

Thank you,
Simone.
