</span>You have now stopped using HTTP and started using some strange<br>
URL-embeded protocol.<br>
<br>
An HTTP proxy cannot help you there. You require a proxy that<br>
understands and acts on the URL-embeded protocol messages.<br>
<br>
It is possible to extend Squid with URL-rewrite helpers that can<br>
translate it into different HTTP URL for passing to (C). BUT, there is<br>
no guarantee of what origin (C) will use to fetch that resource. You<br>
have to *trust* that (C) uses the origin best suited to any request<br>
that it is given, according to the criteria its own admin has set for<br>
"best".<br>
