 ## Idle timeout
 
-Azure Cache for Redis has a 10-minute timeout for idle connections. The 10-minute timeout allows the server to automatically clean up connections that have been leaked or orphaned by client application. Most Redis client libraries have a built-in capability to send `heartbeat` or `keepalive` commands periodically to prevent connections from being closed even if there are no requests from the client application. 
+Azure Cache for Redis has a 10-minute timeout for idle connections. The 10-minute timeout allows the server to automatically clean up leaky connections or connections orphaned by a client application. Most Redis client libraries have a built-in capability to send `heartbeat` or `keepalive` commands periodically to prevent connections from being closed even if there are no requests from the client application. 
 
 If there's any risk of your connections being idle for 10 minutes, configure the `keepalive` interval to a value less than 10 minutes. If your application is using a client library that doesn't have native support for `keepalive` functionality, you can implement it in your application by periodically sending a `PING` command.
