Hi, I have a question regarding the "Upgrade" header. The HTTP/2 specification says: > A server MUST ignore an "h2" token in an Upgrade header field. > Presence of a token with "h2" implies HTTP/2 over TLS, which is > instead negotiated as described in Section 3.3. Does this imply that a server must not (or should not) send an "Upgrade: h2" response header to clients? This question is important for Apache httpd, because version 2.4.20 sends such an "Upgrade: h2" response header to clients that speak HTTP/1.x. Other HTTP/2 server software does not (e.g. nginx, Google's and Twitter's web servers). Related Apache httpd issue: https://bz.apache.org/bugzilla/show_bug.cgi?id=59311 Regards, Michael
