404 errors on images and js file on the XHTML validator dialog

[Trevor]

The problem can be seen in the Telerik demo editor:

   http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultvb.aspx

Steps:

Using Chrome, go to the demo editor.
Click the "XHTML Validator" button in the editor toolbar.
Scroll to the bottom of the dialog.
Notice the two broken images at the bottom of the dialog.
Notice the three 404 errors logged in the Chrome dev console:

GET http://validator.w3.org/http://www.w3.org/QA/Tools/w3c-include.js   404 (Not Found)   Telerik.Web.UI.DialogHandler.aspx:4
GET http://validator.w3.org/http://www.w3.org/Icons/WWW/w3c_home_nb   404 (Not Found)   Telerik.Web.UI.DialogHandler.aspx:4
GET http://validator.w3.org/http://www.w3.org/QA/Tools/I_heart_validator   404 (Not Found)   Telerik.Web.UI.DialogHandler.aspx:4

Is there a workaround for this issue?

Thanks,
Trevor.

Hi Trevor,

Note that the W3C dialog is redirecting to the W3C validation site, where this images are requested from their server. It appear that they had an issue which appears resolved know.

Although, as you noted these images has entirely different URLs and are not related to the content or the RadEditor control at all.

Hi Ianko,

I'm not sure why you say the problem is resolved.  Chrome still reports three 404 errors loading the page:

GET http://validator.w3.org/http://www.w3.org/QA/Tools/w3c-include.js 404 (Not Found) Telerik.Web.UI.DialogHandler.aspx:4
GET http://validator.w3.org/http://www.w3.org/Icons/WWW/w3c_home_nb 404 (Not Found) Telerik.Web.UI.DialogHandler.aspx:4
GET http://validator.w3.org/http://www.w3.org/QA/Tools/I_heart_validator 404 (Not Found) Telerik.Web.UI.DialogHandler.aspx:4

Hello Trevor,

You are correct, the mentioned problem is still the same.

Although, as I mentioned, the W3C service is fetching the HTML content and the RadEditor control is not related to the described images.

Note that they are requested from the HTML code provided by W3C and are set to validator.w3.org domain, which is not hosted on the Telerik servers.

The XhtmlValidator dialog is just using the W3C service and it is a simple iframe redirected to their site. Due to that we do not have the ability to control or modify the requested HTML content and I am unable to provide a possible approach to resolve this behavior.
