> SSL hostname verification fails due to truncated SNI name when escalation
> plugin is used to redirect a failed request (404) from a primary origin
> {{primary.com}} to a secondary origin {{secondary.com}}.
> {code:title=Excerpt from the ATS logs showing the error|borderStyle=solid}
> DEBUG: <SSLNetVConnection.cc:1258 (sslClientHandShakeEvent)> (ssl) using SNI
> name ‘secondary.c'’ for client handshake
