I'm not following why we need this.  Was this code somewhere else before?

[clamy, 2016/04/29 16:07:16]

We need it because we have code to generate a WebHTTPBody (which is a renderer
object), but we don't have code to generate the ResourceRequestBody (which is
the common object that can be used in the browser).

+                      ResourceRequestBody* http_body) {
+  if (exploded.is_null)
+    return false;
+
+  http_body->set_identifier(exploded.identifier);
+  for (auto element : exploded.elements)
+    http_body->AppendExplodedHTTPBodyElement(element);
+
+  return true;
+}
