How to capture this message "Connection Interrupted"

Hi All,

 

I created a TCP profile for the server side, I only changed the idle timeout field, but I'm still receiving the same error message.

 

I was looking at the after commanda page but I don't understand how to use it for my case (capture the "Connection Interrupted" message and resend the request to a friendly/maintenance page).

 

 

many thanks for your help.
