Explainer None Specification https://fetch.spec.whatwg.org/#http-redirect-fetch Summary Update the HTTP request on CORS redirect by removing the request-body-headers and body if the method has changed, and updating the referrer policy. These request updates align with the Fetch spec and match the behavior implemented by Firefox and Safari to improve compatibility. Blink component Blink>Network<https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ENetwork%22> TAG review None - This change is a bug fix to align with the Fetch spec and other browser behavior. TAG review status Not applicable Risks Interoperability and Compatibility The risk is low for updating the request on CORS redirect to align with the spec and other browsers, but there is still some compatibility risk in modifying existing behavior.
