removeResponseHeader method
Removes the given default headers of the server's responses, as
HttpHeadersValues.removeValues does: a list removes each of its
values, a value matches exactly, or ignoring case if nothing matches
exactly, and a null value removes the header, whatever its values.
Implementation
void removeResponseHeader(Map<String, Object?> headers) {
headers.keys.forEach(checkHeaderName);
server?.defaultResponseHeaders.removeValues(headers);
}
