Hello Mark, In continuation of my previous mail, *Just in a while, I could replicate the issue on my local machine by installing Tomcat 9 explicitly [Now, I could see cache-control headers are being transmitted to Varnish of server2]*
*Point to note here,* *Issue not replicated through integrated tomcat of Spring-boot* *Issue replicated by installing Tomcat 9 on my local machine and building corresponding war files.* *I suspect, there is the configuration of Tomcat which is responsible for setting Cache-control and pragma header by default to outgoing requests.* *Kindly check and let me know if I am missing anything.* We have tried replicating the issue by using a local machine (spring-boot > application as an API-1 with integrated tomcat) to hit API-2 which is on > Server2, in this case, Cache-Control headers are *not being transmitted* > to Varnish of server2. > Thanks & Regards, Uday Kumar
