S3 static website RedirectAllRequestsTo throws InvalidURI instead of redirecting some requests

Question

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 400 Bad Request

400 Bad Request

Code: InvalidURI
Message: Couldn't parse the specified URI.

Answer

`%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 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* Trying 52.218.97.236:80... * Connected to static.swyd.ca.s3-website-eu-west-1.amazonaws.com (52.218.97.236) port 80 (#0) > GET /%C0 HTTP/1.1 > Host: static.swyd.ca.s3-website-eu-west-1.amazonaws.com > User-Agent: curl/8.1.2 > Accept: */* > < HTTP/1.1 400 Bad Request < x-amz-request-id: D5RTSV1DKFXB8PRQ < x-amz-id-2: DLiV+/FbrPj5myRI7HhUuBJb3M= < Content-Type: text/html; charset=utf-8 < Date: Fri, 18 Aug 2023 08:11:20 GMT < Server: AmazonS3 < Content-Length: 348 < Connection: close ``` 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 Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0* Trying 52.218.37.188:80... * Connected to static.swyd.ca.s3-website-eu-west-1.amazonaws.com (52.218.37.188) port 80 (#0) > GET /%C3%80 HTTP/1.1 > Host: static.swyd.ca.s3-website-eu-west-1.amazonaws.com > User-Agent: curl/8.1.2 > Accept: */* > < HTTP/1.1 301 Moved Permanently < x-amz-id-2: fzEpLLxY4XH+6/dfgzCCfEaQ9AaH++= < x-amz-request-id: CDSCQ3ND8 < Date: Fri, 18 Aug 2023 08:14:00 GMT < Location: http://swyd.ca/%C3%80 < Server: AmazonS3 < Content-Length: 0 ```
