Hi, Atul
The content for the failed HTTPS request is this
------------------
500 proxy connect failed: PROXY ERROR HEADER, could be non-SSL URL:
HTTP/1.1 403 Forbidden
Date: Wed, 27 Sep 2006 15:01:50 GMT
Content-Length: 298
Connection: close
Content-Type: text/html; charset=iso-8859-1

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>403 Forbidden</title>
</head><body>
<h1>Forbidden</h1>
<p>You don't have permission to access 207.154.17.141:80
on this server.</p>
<hr>
----------------------------
I searched the error message "PROXY ERROR HEADER, could be non-SSL URL" 
through google. There is not a solution for this.

Thanks
