No call to clientaccesspolicy.xml

I have an ASP.NET MVC 3 Web application which has Sil开发者_Python百科velight 4 ,which provides video streaming, in it. It works well in localhost, that is calls clientaccesspolicy.xml file. However after I publish it to my server, it doesn't call the clientaccesspolict.xml file, and not works!

What sould I do?

If they are within the same domain then it shouldn't need to access the clientaccesspolicy.xml

Here's how I'd debug this problem:

Use Fiddler and watch for the request to ClientAccessPolicy.xml. Does it succeed? Does it 404? If it 404s, check the URL and verify your webhost is configured to serve XML files, and verify the file is where it's supposed to be.
