varnishtest "A test for http-request-buffer option"
feature ignore_unknown_macro
# 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.
