  custom error pages

  Jan 18, 2021 08:17 AM|EyalD|LINK

  Hi All

  we have a custom error pages in our sites.

  for some reason when opening dev tools (in browser) the error pages that configured as aspx returns 404 but the htm\html pages returns 200.

  why is that?

  thanks

  Hi EyalD,

  If you set the responseMode is ExecuteURL, it will return 200. Because it is also a request for error page.

  <httpErrors errorMode="Custom">
              <remove statusCode="404" subStatusCode="-1" />
              <error statusCode="404" prefixLanguageFilePath="" path="/404.html" responseMode="ExecuteURL" />
  </httpErrors>

  

  Set the responseMode to File will make status code to 404, not 200.

   <httpErrors errorMode="Custom">
              <remove statusCode="404" subStatusCode="-1" />
              <error statusCode="404" prefixLanguageFilePath="" path="404.html" responseMode="File" />
   </httpErrors>

  

  Best regards,

  Because IIS errors (html pages, etc). and asp.net errors handling are very different beasts. You will need to configure both to have a complete site.
