+//  HTTP headers test
+//  Response headers can be changed after they have been received, e.g. empty
+//  headers are deleted, some duplicate header are merged (if no error is
+//  thrown), etc.
+//
+//  The "original header" is introduced to hold the header array in the order
+//  and the form as they have been received from the network.
+//  Here, the "original headers" are tested.
+//
+//  Original headers will be stored in the cache as well. This test checks
+//  that too.
+
+// Note: sets Cc and Ci variables
