Error handling and logging

We don't think any "enterprise application" can truly be called "enterprise" if it doesn't handle errors well and notify someone to address them. In an ASP.NET site, there are basically two forms of errors—errors that you have caught, and the ones you couldn't. Pretty simple, right? Well, not so fast! Whether you have trapped an error or not, the user of your application is still going to end up with some form of disruption in their surfing experience. So we need a way to not only provide users with a smooth disruption but also to fix the disruption so that it doesn't happen again.
