In chapter 18 on page 662 you mention to consider setting the retail attribute of the deployment element within the machine.config to true as follows:
Feel free to correct me If I'm wrong, but won't the attributes set within the web.config for compilation, customErrors, and trace override what's in the machine.config? Or in order to do so would you need to utilize a <clear /> element as such in the example at the bottom of page 660 for the compilation, customErrors, and trace elements within the web.config to override the settings in the machine.config?
Not that it would happen on a production box, but what if you had a legitimate need to override the settings in the machine.config within the web.config for say just one out of ten websites hosted on a server.
I'm hoping you could clarify this for me.
