<Connector port="7100" protocol="org.apache.coyote.http11.Http11NioProtocol" compression="1024" compressableMimeType="text/html,text/xml,text/json,text/plain, application/xml,application/json,image/svg+xml" connectionTimeout="20000" maxPostSize="0"redirectPort="7101" />
Restart Apache Tomcat/DeployR.
