Puzzled at request_t->link_count. :-(

Hi, pals!

I search for the source files that contain link_count. And
I think the link_count is the number of the link a request
is having now. I think link here means the URL of the origin server
that the request client wants to connect. Am I correct?

But what puzzled me most is that a request can link to more
than one origin servers. Look at the following codes,

request_t *
requestLink(request_t * request)
{
    assert(request);
    request->link_count++;
    return request;
}

How can that happen?

Best regards,
George Ma
