A TimeoutException is an exception that is thrown when a request takes longer than a specified amount of time to process. This can happen for a number of reasons, such as a slow database connection, a long-running operation, or a network outage.
In ASP.NET MVC projects, TimeoutException can be handled by using the following approaches:
Set a global timeout: You can set a global timeout for all requests in your application by setting the executionTimeout attribute in the web.config file. For example:
Code snippet
andlt;httpRuntime executionTimeout="30" />
This will cause the application to throw a TimeoutException if any request takes longer than 30 seconds to process.
Use a custom filter: You can also use a custom filter to handle TimeoutException. This filter can be used to log the exception, display a custom error message, or redirect the user to a different page.
Use an AsyncController: AsyncControllers can be used to handle long-running operations without blocking the UI thread. This can help to prevent TimeoutException from being thrown.
Here is an example of how to use an AsyncController:
Code snippet
public class HomeController : AsyncController
{
    public async Taskandlt;IActionResult> Index()
    {
        // Do some long-running operation here.
        // Return a success response.
        return View();
    }
}
By using these approaches, you can help to prevent TimeoutException from occurring in your ASP.NET MVC projects.
Here are some additional tips for handling TimeoutException:
Log the exception: It is important to log TimeoutException so that you can track and troubleshoot the problem.Display a custom error message: You can display a custom error message to the user when TimeoutException is thrown. This can help to provide the user with more information about the problem.Redirect the user to a different page: You can redirect the user to a different page when TimeoutException is thrown. This can help to prevent the user from seeing a blank page or an error message.
By following these tips, you can help to handle TimeoutException in a way that is both informative and user-friendly.
