<div>Hi Adrian£¬</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp;&nbsp; What you said is really the existing problem. Because without http_proxy, I cannot connect to W3C.org.</div>
<div>&nbsp;&nbsp;&nbsp; </div>
<div>&nbsp;&nbsp;&nbsp; This morning,I move my PC to another place, where it can connet to w3c directly ,need not any http_proxy. Then SIPSIMPLEClient and OpenXCAP interoperate successfully!</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp;&nbsp; Thank you all~&nbsp; :)</div>

<div>Hi Sa¨²l,</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp;&nbsp; Thanks for your reply ,but I&#39;m&nbsp; afraid that http_proxy is not the root of this problem.</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp;&nbsp; Because I have do the same test:</div>

<div>So, I think whether it&nbsp;is related to my XCAP-ROOT,&nbsp;because&nbsp;xcap-icon cannot connect to my xcap server. And I don&#39;t know how a http_proxy can&nbsp;impact xcap-icon function.</div>
<div>&nbsp;</div>
<div>&nbsp;</div>
<div>This is my sipsimpleclient configuration, you can use it to have a test.</div>
