How to: Display Safe Error Messages Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 When your application displays error messages, how to show success message in asp net it should not give away information that a malicious user might find helpful in attacking your system. For example, if your application unsuccessfully tries to log in to a database, it should not display an error message that includes the user name it is using. There are a number of ways to control error messages, including the following: Configure the application not to show verbose error messages to remote users. (Remote users are those who request pages while not working on the Web server computer.) You can optionally redirect errors to an application page. Include error handling whenever practical and construct your own error messages. In your error handler, you can test to see whether the user is local and react accordingly. Create a global error handler at the page or application level that catches all unhandled exceptions and routes them to a generic error page. That way, even if you did not anticipate a problem, at least users will not see an exception page. To configure the application to turn off errors for remote users In the Web.config fil

Join them; it only takes a minute: Sign up Best practice to return errors in ASP.NET Web API up vote 164 down vote favorite 86 I have concerns on the way that we returns errors to client. Do we in asp net return error immediately by throwing HttpResponseException when we get an error: public void Post(Customer customer) { if (string.IsNullOrEmpty(customer.Name)) { throw new HttpResponseException("Customer Name cannot be empty", HttpStatusCode.BadRequest) } if (customer.Accounts.Count == 0) { throw new HttpResponseException("Customer does not have any account", HttpStatusCode.BadRequest) } } Or we accumulate all errors then send back to client: public void Post(Customer customer) { List>(errors, HttpStatusCode.BadRequest); throw new HttpResponseException(responseMessage); } This is just a sample code, it does not matter either validation errors or server error, I just would like to know the best practice, the pros and cons of each approach. c# rest asp.net-web-api share|improve this question edited Aug 11 at 1:28 abatishchev 57k56214353 asked May 24 '12 at 7:00 Cuong Le 41.3k1372124 1 See stackoverflow.com/a/22163675/200442 you sh
are usually handled in MVC Controller actions and Web API Controller actions. When an exception occurs, application user somehow informed about the error and optionally reason of the error. If an error occured in a regular HTTP request, an error page is shown. If an error occured in an AJAX request, server sends error information to the client and then client handles and shows the error to the user. Handling exceptions in all web request is a tedious and repeating work. ASP.NET Boilerplate automates this. You almost never need to explicitly handle any exception. ASP.NET Boilerplate handles all exceptions, logs them and returns appropriate and formatted response to the client. Also, handles these response in the client and show error messages to the user. Enabling Error Handling To enable error handling for ASP.NET MVC Controllers, customErrors mode must be enabled for ASP.NET MVC applications.
