When a string is sent in the response body, GET request has only Content-Length whereas HEAD request has both Transfer-Encoding and Content-Length.
Expected Behavior
Should remove Transfer-Encoding header for HEAD request too, as it is being done for GET request.
Actual Behavior
Both Transfer-Encoding and Content-Length are being sent.
Worth noting
https://tools.ietf.org/html/rfc7230#section-3.3.2
A sender MUST NOT send a Content-Length header field in any message
that contains a Transfer-Encoding header field.
Steps to Reproduce
@GetMapping("/message")
public ResponseEntity<String> getMessage() {
return ResponseEntity.ok("foo");
}curl -v -X GET http://localhost:8080/message
Note: Unnecessary use of -X or --request, GET is already inferred.

Warning: Setting custom HTTP method to HEAD with -X/--request may not work the
Warning: way you want. Consider using -I/--head instead.
