Let's say the user surfs to
http://mysite.com/some-path and encounters error 500 which leads to a custom error page.
What is the best practice regarding the URL shown in the address bar while in the error page - should I leave
http://mysite.com/some-path or should I change it to
http://mysite.com/custom-error.aspx? Is there a good reason not to leave the URL as is?
