Showing 302 redirection error instead of 404

[zco_seo]

Moz is showing 302 error instead of 404 in the Crawl Diagnostics Summary report. But there is no such page uploaded ever to the site. Please let me know why this is happening.

The reason is because of the way that your server is set up. You can read more about how asp handles errors here http://www.colincochrane.com/post/2008/01/ASP-NET-Custom-Errors-Preventing-302-Redirects-To-Custom-Error-Pages.aspx
