+# This reg-test checks the full support of HTTP protocol upgrade, using a GET
+# method and a Connection: Upgrade header. The equivalent mechanism has been
+# defined in rfc8441 for HTTP/2 using CONNECT and a new pseudo-header
+# :protocol. Check that haproxy handles properly h1/h2 translation of protocol
+# upgrade requests and responses.
