You could try using Javascript Bridge . I have not tried this approach but you could use ajax call and then "push" to SL via the JS bridge.

Create an util class for server side such as Util.DoRequest(string address):string

From msdn :

return readStream.ReadToEnd to your client over WCF RIA Services.(Domain Service Class)

By this way if your server has access this RESTful service or it's already located there you do not need any crossdomain configuration for your xap .

HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);

        // Set some reasonable limits on resources used by this request
        request.MaximumAutomaticRedirections = 4;
        request.MaximumResponseHeadersLength = 4;
        // Set credentials to use for this request.
        request.Credentials = CredentialCache.DefaultCredentials;
        HttpWebResponse response = (HttpWebResponse)request.GetResponse ();

        Console.WriteLine ("Content length is {0}", response.ContentLength);
        Console.WriteLine ("Content type is {0}", response.ContentType);

        // Get the stream associated with the response.
        Stream receiveStream = response.GetResponseStream ();

        // Pipes the stream to a higher level stream reader with the required encoding format. 
        StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);

        Console.WriteLine ("Response stream received.");
        Console.WriteLine (readStream.ReadToEnd ());
        response.Close ();
        readStream.Close ();

Instead of trying unknown ways, it is better to place a cross domain policy file in the server. Why you don't need to have a cross domain policy file and client access file in the server? Is there any specific reason for it?
