To improve API call response times, HTTP has a feature called "[Keep-Alive](https://en.wikipedia.org/wiki/HTTP_persistent_connection)". These are connections that allow your application to hold a TCP connection open between your application and Validic servers once an API call has completed. When your application needs to send another API call, it can use this idle "Keep-Alive" connection rather than creating a new TCP connection. This eliminates the need to create a new connection thereby saving the time and resources needed to create it. This will improve Validic's average response times for your application at large.

To enable HTTP Keep-Alive for your application, you may check this resource on how to enable it for your application [http://www.feedthebot.com/pagespeed/keep-alive.html](http://www.feedthebot.com/pagespeed/keep-alive.html). There are also many other resources on the web regarding how to enable the use of HTTP Keep-Alive connections specific to your application.
