WireMock supports sending CORS headers for stub responses.
Add configuration for enable automatic sending of CORS headers on stub responses like in WM.
Use case
Consider developing SPA - for exaple react app. Application during development is avaiable on port 3000, but View as Published app is available on port 4502. It is not possible to handle it- because of CORS. You can add headers on mocks, but easier way would be to have possibility on tool by default
