Use <customErrors> web-config element for redirection in case of specific or any error.

For logging you can use Application_Error event of HttpApplication class in Global.asax.

Hi Tia,

above experts are right !!

You need to handle the internal server errors through page or application level, the better way you can go with Application level event in Global.asax

protected void Application_Error(Object sender, EventArgs e)
{
  // At this point we have information about the error
  HttpContext ctx = HttpContext.Current;

  Exception exception = ctx.Server.GetLastError ();

  string errorInfo =
     "<br>Offending URL: " + ctx.Request.Url.ToString () +
     "<br>Source: " + exception.Source +
     "<br>Message: " + exception.Message +
     "<br>Stack trace: " + exception.StackTrace;

//Create a separate method “Exceptionlogging” which logs the     //exception through enterprise library or write the error info in a XML

  Exceptionlogging(errorInfo);
 
  // --------------------------------------------------
  // To let the page finish running we clear the error
  // --------------------------------------------------
  ctx.Server.ClearError ();
}

Then to redirect the error page 500.aspx, you need to set Custom error in web.config, Even you can set the more specific error redirection, for 404 error it will go to Pagenotfound.aspx

<customErrors mode="On" defaultRedirect="~/errors/500.aspx">
     <error statusCode="404" redirect="~/errors/PageNotFound.aspx" />
</customErrors>

Hi,

In web.config I have written

<customErrors mode="On" defaultRedirect="~/errors/500.aspx">
                  <error statusCode="404" redirect="~/errors/PageNotFound.aspx" />
                  <error statusCode="500" redirect="~/errors/500.aspx" />
            </customErrors>
            
            
            <customErrors mode="On" defaultRedirect="~/errors/500.aspx">
                              <error statusCode="404" redirect="~/errors/PageNotFound.aspx" />
                              <error statusCode="500" redirect="~/errors/500.aspx" />
            </customErrors>
            
            
and in global.asax file i have written below code:

void Application_Error(object sender, EventArgs e)
    {        
       
        HttpContext ctx = HttpContext.Current;

        Exception exception = ctx.Server.GetLastError();
        Logger.Error(String.Format("{0}: errorInfo:{1}", ctx.Request.Url.ToString(), exception));
        ctx.Server.ClearError();          
       
    }
   
   
    But it is not forwarding the 500 errors to 500.aspx file
   

Please guide

Many Thanks

ctx.Server.ClearError();
