cross-domain hosted Silverlight app not loading in a https webpage

Question

I want to provide silverlight app to my customer while hosting the app at my own site for streamlined maintenance.

• my Silverlight .xap is hosted in, let say, domain me-supplier.com
• i want to embed it in, let say, domain my-customer.com

It works perfectly for http://my-customer.com, not for https://my-customer.com

• i have added the (me-supplier.com hosted) cross domain silverlight policy file to allow my-customer.com
• i have configured the mime types for .xap
• the silverlight app needs html dom access so the iframe approach is not viable i believe.

this works for javascript code, so why not for silverlight ? any idea, workaround ?

Answer 1

Is the silverlight app also on https? If not, you might be hitting a security wall which does not allow to intermix http and https application domains

Answer 2

I think the answers to this question may explain it.

Generally HTTPS doesn't like you drawing data between domains within a page because the certificate is tied to the current domain.
