This article provides a detailed overview of ASP.NET custom
error pages and several different methods to implement them. When an error
will occur, end users should always have a view of meaningful and friendly error
pages. At the same time, it is also important that people on the other end (the
administrator or developers) are alerted about problems. Using the Custom Error
Page we can also provide the page with the site’s look and feel. Custom error
page design becomes a normal part of site design.
