Localhost WWW proxy issue (can't bypass?)

When using WWW and connecting to localhost I get a 407 proxy authentication error. We are behind a proxy. How do we supply proxy creds in this case or bypass it completely since we're just trying to hit localhost and do some testing?

We updated our LAN settings via IE to bypass proxy for local web resources but that didn't seem to fix it. We're running an XAMPP installation on our work station and we're running unity and the WWW call from (same box) for this test.

//do a GET request on the url w/ some custom headers Dictionary headers = new Dictionary(); headers.Add("X-Testing", "worked?");

WWW www = new WWW("https://localhost/testing/test.php?test=1", null, headers);
