Hi Maxim,

Thanks for the insight! I had a hunch on the keepalive setting from nginx to tomcat, but did not really find anything in the document about that. I will give it a try and let you know the results. I am not sure if I will be able to use this keepalive in production as it requires upstream config and differs from the way we have architect Nginx configuration.

I am using nginx as a dynamic proxy which routes the clients calls (primarily web service calls) to different servers depending on the key the client passes via cookie or http headers. The url's are in a map in the below form

map $http_void $header_based_url{
default "no_http_header";
key1 server_instance_1_url;
key2 server_instance_2_url;
......
}

location /xxx {
proxy_pass $header_based_url;
}
And to make it more simple to add / maintain the server url's, the URL's are stored in a flat file

I am not sure how I can use the keepalive over here other than the upstream or how do I make this upstream config compatible.

Regards
