[jira] [Commented] (TS-3476) Add a log tag for APLN/NPN negotiated protocol

["Leif Hedstrom (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-3476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14535061#comment-14535061 ] 

Leif Hedstrom commented on TS-3476:
-----------------------------------

As sudheer points out, we should make sure we make any such tags compatible with both client and server side going forward (we only support client side right now). So maybe

%<ctnp> - Client TLS Negotiated Protocol
%<stnp> - Server TLS Negotiated Protocol

> It seems crucial to be able to log which protocol handler was negotiated with ALPN (and perhaps NPN as long as we support it). This could simple be the string that was negotiated by the client/server in the TLS handshake. For example, with HTTP/2, it would be "h2" (or "h2-14" with some browsers).
> A suggested log tag name would be %<alpn> which seems clear enough to me and easy to remember :).
