	FYI - this patch to SesameHttpProtocolConnector.cs fixed the issue for us. Basically this forces authentication on every single HTTP request (so we never hit a 401 response unless the credentials were invalid):</p>
<p>
	&nbsp;</p>
<p>
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //Add Credentials if needed<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (this._hasCredentials)<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //NetworkCredential credentials = new NetworkCredential(this._username, this._pwd);<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //request.Credentials = credentials;<br />
	&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;string credentials = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(this._username+ &quot;:&quot; + this._pwd));<br />
	&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;request.Headers.Add(&quot;Authorization&quot;, &quot;Basic &quot; + credentials);<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</p>
<p>
	This obviously won&#39;t work in cases where other (non-Basic) authentication is in place (Digest, Negotiate, Kerberos, NTLM)..</p></td>
