Prevent Tomcat from sending header "Connection: close"

Question

My Tomcat Websocket Server has the attribute "Connection" double in the reply header for connections via https: "upgrade" and "close". Not for connections via http, only "upgrade" here. This will cause Safari to disconnect. How can I prevent "Connection: close" from appearing in the header?

Connector configuration :

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="" keystorePass="" />

Can I create an custom implementation of AbstractHttp11Processor where the "Connection: close" is set? I use Tomcat 7.0.76. — Jan Knoblauch, May 25 '18 at 12:35
share your [Connector](http://tomcat.apache.org/tomcat-7.0-doc/config/http.html) configuration — Eugène Adell, May 25 '18 at 13:32
There is no problem to connect via https to webpages but websocket via wss is not working. — Jan Knoblauch, May 25 '18 at 16:33

I could solve the problem by changing to Tomcat 9.0.8. I continue to use the same connector configuration.
