Allowing https access to your services from your Silverlight apps by Roberto

If you want your services to be accessed by your Silverlight applications using https protocol using this on your clientaccesspolicy.xml file won’t be enough.

<domain uri="*"/>

According to MSDN you have to specify the protocols you want to support, like this:

<?xml version="1.0" encoding="utf-8"?>
<access-policy>
    <cross-domain-access>
        <policy>
            <allow-from http-request-headers="*">
                <domain uri="http://*"/>
                <domain uri="https://*"/>
            </allow-from>
            <grant-to>
                <resource path="/" include-subpaths="true"/>
            </grant-to>
        </policy>
    </cross-domain-access>
</access-policy>

Cheers!
