error handling in asp.net MVC3

Question

I have created an MVC3 application and added cutomerrors attribute on in web.config. It works in chrome and Firefox but When I run it in IE9, I get

The website cannot display the page

HTTP 500

Most likely causes: •The website is under maintenance. •The website has a programming error.

What you can try:

<?xml version="1.0"?>

There is a known problem in Internet Explorer versions where a custom error page has to be at least 512 bytes. While this usually applies to old IE versions and usually resulting in a 404 error page, I'd recommend to ensure that your custom error page is, say 1 kB of size. You might put some HTML comments in or something. Just to ensure that it has nothing to do with that old IE bug.

Just one reference of many: http://perishablepress.com/press/2008/01/21/important-note-for-your-custom-error-pages/

thanks it worked. One issue however is that as I am using VS developement server. so when I run my MVC application, It hits the place where exception has occurred in controller and then I press enter to show error page. can't It go directly to error page ?

thmshd Over a year ago

what do you mean with "it hits the place"? Do you mean VS holds in debugger? If so, you might use your Visual Studio Main Menu "Debug" » "Exceptions..." and there you can setup which exceptions you want to handle, this might help. For more control, you might look here: stackoverflow.com/questions/183316/asp-net-mvc-handleerror/… (But this is another story)

Thanks! After countless hours of trying to figure it out... Gotta love IE. +1

That's the inbuilt IE error page. Can you post your web.config so we can see what you have in there?

<customErrors mode="On" defaultRedirect="/Home/Error">
  <error statusCode="403" redirect="/Home/NoAccess" />
  <error statusCode="404" redirect="/Home/NotFound" />
  <error statusCode="500" redirect="/Home/Internal" />
</customErrors>

Is what I'd expect to see in the web config. I'm not sure what page is being shown in the other browsers.

I guess IE9 is expecting some content to be returned, try adding the Internal action and view to your home controller and specifying defaultRedirect="/Home/Internal" and see if that works.
