+# This reg-test is uses to test respect of the websocket protocol according to
+# rfc6455.
+#
+# In particular, a request/response without a websocket key must be rejected by
+# haproxy. Note that in the tested case (h1 on both sides), haproxy does not
+# validate the key of the server but only checks its presence.
+#
+# For the case h2 client/h1 server, haproxy would add the key and validates it.
+# However, there is no way to check this case quickly at the moment using vtest.
