Summary
Client-handled Server Action redirects currently return a
303without aLocationheader and may include a streamed RSC response body. Some HTTP intermediaries reject this response or strip its body because it looks like an HTTP redirect.Return
200for client-handled Server Action redirects while continuing to usex-action-redirectand the RSC response. Progressive-enhancement form submissions still return a standards-compliant303withLocation.Fixes #92882
Fixes #74026
