+feature ignore_unknown_macro
+
+#REQUIRE_VERSION=1.6
+
+# This test checks HTTP request buffering feature.
+# We run one server s1 which can serve only one client (no -repeat argument here).
+# c1 client uses a malformed request which is not transferred to s1 server
+# thanks to "http-buffer-request". If this was the case, c2 client
+# could not connect to s1 server and this would lead to make this test fail.
