WebResource.axd causes http/https mixed content error

I am having a problem only in IE-9 where 
In IE-9 only, I am getting an error on one of my pages: 
Only secure content is displayed
I can work around the problem by telling IE to allow mixed content:
IE | Internet Options | Security | Internet | Custom level | Settings | Misc | Display mixed content: Enable

The problem stems from the fact that the <syncfusion:Window... control is generating this call:
SEC7111: HTTPS security is compromised by http://www.mydomain.com/WebResource.axd?d=64euDdc4i...

My site uses https, but the WebResource.axd uses http, thus the error.  To fix it I either need to make the WebResource.axd use https, or make the path relative, or perhaps something to do with an httphandler in web.config

Any ideas?

Hi Jeff,


Thanks for contacting Syncfusion forums.


We would like to let you know that we are not able to change “webresource.axd” to use “https”, because this handler is common for all our controls and we cannot change this specifically for a control. Could you please share your online link which reproduces the issue? So that we would analyze the issue in your online link.


Note: For your information, please refer the following site which is combination of https and http, https://www.syncfusion.com/account/register (i.e the online site uses https whereas the handler of Captcha control within the page uses http)


Please let us know if you have any other concerns.
