S3 static website RedirectAllRequestsTo throws InvalidURI instead of redirecting some requests

0

I have a bucket configured to RedirectAllRequestsTo a different domain. No special routing rules or nuance, just redirect everything, always. But I find that some requests throw an error from this s3 bucket because they aren't parseable! I would expect it to redirect regardless, and let the other domain deal with that.

$ aws s3api get-bucket-website --bucket www.example.com
{
    "RedirectAllRequestsTo": {
        "HostName": "example.com",
        "Protocol": "https"
    }
}
$curl www.example.com.s3-website-us-west-2.amazonaws.com/%C0
<html>
<head><title>400 Bad Request</title></head>
<body>
<h1>400 Bad Request</h1>
<ul>
<li>Code: InvalidURI</li>
<li>Message: Couldn&#39;t parse the specified URI.</li>
...
$ curl -i www.example.com.s3-website-us-west-2.amazonaws.com/foo
HTTP/1.1 301 Moved Permanently

Is there any way to actually redirect all requests?

%C0 is the url encoding for À in the Windows-1252 encoding scheme. You should encode your url-query strings in utf8.

For À this would be %C3%80.

I setup my redirect as follows (same as yours just left out the protocol.

% aws s3api get-bucket-website --bucket static.swyd.ca --region eu-west-1
{
    "RedirectAllRequestsTo": {
        "HostName": "swyd.ca"
    }
}

When I test this with %C0 it fails:

% curl -vko /dev/null http://static.swyd.ca.s3-website-eu-west-1.amazonaws.com/%C0
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

Using UTF8 encoding it works:

% curl -vko /dev/null http://static.swyd.ca.s3-website-eu-west-1.amazonaws.com/%C3%80
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

    Appreciate your response, but this is different from my question. I can't control the things people type into their URL bar, and I'm not trying to. I'm trying to understand why the bucket returns a 400 ever given that I've set it to always redirect.
