Specifies whether WebAssembly modules can be sent cross-origin (obsolete)

OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge version 98.

Supported versions

  • On Windows and macOS since 95, until 98

Description

Specifies whether WebAssembly modules can be sent to another window or worker cross-origin. Cross-origin WebAssembly module sharing was deprecated as part of the efforts to deprecate document.___domain, see https://github.com/mikewest/deprecating-document-___domain. This policy allowed re-enabling of cross-origin WebAssembly module sharing. This policy is obsolete because it was intended to offer a longer transition period in the deprecation process.

If you enable this policy, sites can send WebAssembly modules cross-origin without restrictions.

If you disable or don't configure this policy, sites can only send WebAssembly modules to windows and workers in the same origin.
