Catching exceptions

1. Application_Error in Global.asax.cs

protected void Application_Error(object sender, EventArgs e)

{

     HttpContext.Current.Response …

     HttpContext.Current.Response.StatusCode  ….

     System.Net.HttpStatusCode.InternalServerError  ….

     // For custom error page you can do something like this

      var errorPageUrl = GetGeneralErrorPage();

      HttpContext.Current.Server.TransferRequest(errorPageUrl);

}

2. Pipeline

Try this.

1. Create a class to catch and log exceptions. Something like this

public class HandleMvcException : ExceptionProcessor

    {

        public override void Process(ExceptionArgs args)

        {

            var context = args.ExceptionContext;

            var httpContext = context.HttpContext;

            var exception = context.Exception;

            if (context.ExceptionHandled || httpContext == null || exception == null)

            {

                return;

            }

httpContext.Request.Url…

exception.Source…

exception.Message…

exception.StackTrace…

        }

    }

2. See if you can find where the exception handling pipeline is with Sitecore and replace a Sitecore processor with yours via a config patch file.

<pipelines>

    <mvc.exception>

      <processor type="Sitecore.Mvc.Pipelines.MvcEvents.Exception.ShowAspNetErrorMessage, Sitecore.Mvc">

        <patch:attribute name="type">Igt.Pipelines.HandleMvcException, Igt</patch:attribute>

      </processor>

    </mvc.exception>

  </pipelines>

Thanks!
