Squid proxy authentication problem

From: Sparks, James <james.sparks_at_oce.com>
Date: Thu, 12 Feb 2009 17:37:37 -0700

I'm having a problem getting Proxy authentication from our Squid server (squidNT/2.7.STABLE5). I'm using libCurl version 7.19.3. The Curl proxy options currently set are (company passwords replaced by *****):
   curl_easy_setopt(m_CurlHandle, CURLOPT_PROXY, "http://10.10.1.46:3128/");
   curl_easy_setopt(m_CurlHandle, CURLOPT_USERNAME, "user1");
   curl_easy_setopt(m_CurlHandle, CURLOPT_PASSWORD, "*****");
   curl_easy_setopt(m_CurlHandle, CURLOPT_PROXYAUTH, CURLAUTH_ANY);
The response code returned by curl_easy_perform is CURLE_OK.
I hard link with the libCurl and OpenSSL libraries and am building on a Windows platform using VS 2005.

Here is my log file with curl verbose turned on:
