iirc, we had to handle this case specifically for middleware Redirects. Can you verify that it works with this change?

Yeah, i`ve tested it by patching 2.3.6 version. Maybe I need to cover this case by some tests? Do you have any contributing docs?

I believe we have this covered

App: https://github.com/sst/open-next/blob/main/examples/app-router/middleware.ts#L8

.get("location")
?.replace("http://localhost:3000", `https://${req.headers.host}`);
resHeaders.location = resHeaders.location?.replace(
"http://localhost:3000",
`https://${req.headers.host}`,
);
// res.setHeader("Location", location);
return {
body: "",
type: internalEvent.type,
statusCode: res.statusCode,
headers: {
...resHeaders,
Location: location ?? "",
