The Uniform Messaging Policy (UMP) enables cross-site messaging that avoids
Cross-Site-Request-Forgery and similar attacks that abuse HTTP cookies and other
credentials. For example, content from customer.example.org can
safely specify requests to resources determined by
service.example.com. Rather than restricting information retrieval
to a single origin, as the Same Origin Policy almost does, the Uniform Messaging
Policy supports origin independent messaging.
