I am new to Nginx, so know very little about it.

My requirement is I need to make a service call but along with proxy passing
that request, I need to make call to another service/servlet. For this I
decided to use Echo module to use the echo_subrequest_async option.

However the subrequest is not working and even simple echo print is not
working. Where does echo "hello" supposed to go? to the client side (my

nginx config

  server {
     listen 80;
     server_name localhost;
     location /mywebapp {
        default_type "text/plain";
        echo "in webapp call, should not happen";
        proxy_pass http://localhost:8080/mywebapp/;

     location /messaging-service {
        default_type "text/plain";
        echo "in the messaging service call";
        echo_subrequest_async  GET '/mywebapp/second';
        proxy_pass http://localhost:8090/messaging-service/;

     location /mywebapp/second {
        echo "Going to keep sesson alive !!";
        proxy_pass http://localhost:8080/mywebapp/second/;
