Why does Tomcat 9 have established connections on localhost

  • 772

I'm trying to understand why Apache Tomcat 9 has certain established connections that are via localhost. I'm using the Apache Tomcat 9 on windows. See below, I'm looking at the TCP/IP section in process explorer for the Tomcat9.exe process.

What caused these sockets to be established?

tomcat 9 tcp/ip

socket tomcat9

  1. Some environments - such as Java and Tomcat by extension - tend use the loopback address for inter process communication. That's the most likely cause.
