disable debug mode, enable remote custom errors, and disable trace in one declaration

For security purposes, we should not put websites into  production environment with debug mode enabled nor trace enabled. I got this tip from a book published by SAMS. On the production server, add the following element inside the system.web section of the machine.config file:

<deployment retail=“true”/>

Adding this element disables debug mode, enables remote custom errors, and disables tracing on all of the ASP.NET websites on that server.
