ELMAH (Error Logging Modules and Handlers)

HTTP modules and handlers can be used in ASP.NET to provide a high degree of componentization for code that is orthogonal to a web application, enabling entire sets of functionalities to be developed,packaged and deployed as a single unit and independent of an application. ELMAH (Error Logging Modules and Handlers) illustrates this approach by demonstration of an application-wide error logging that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine,without any need for re-compilation or re-deployment.The end-user(if allows) can view the exception/inner exception logged in the server,Its description and even the screen-shot of the
error page
