Silverlight 5 trust application issue

Question

In silverlight5 beta, it supports trust application which allows loading local files. I tried and it works fantastic in both OOB and in browser mode. One question is that, when put my cap on the server, it works fine in OOB mode but doesn't work in browser. I think debugging locally and deployment is different. Is there a way to request the trust in browser as I tried locally?

Thanks, Howard
