 varnishtest "Test the proper interaction between http-reuse and backend in transparent mode"
 feature cmd "$HAPROXY_PROGRAM -cc 'feature(TPROXY)'"
 
-# If backend is used with the transparent mode, the connection are considered
-# as private and should only be reused for requests of the same session.
-# This is similar to the http-reuse never mode
+# Verify that connections made to a backend in transparent mode with
+# "http-reuse never" are only reused with that client, and those with
+# "http-reuse always" are properly shared across subsequent clients.
