URL redirect/rewrite about amazon-cloudfront-functions HOT 1 OPEN

Would something like this work for your use case?

function handler(event) {

    var request = event.request;
    var uri = request.uri;
    var host = request.headers.host.value;
    
    if(!uri.includes('/partners/')){
        uri = uri.toUpperCase()
    
        var response = {
            statusCode: 302,
            statusDescription: 'Found',
            headers:
                { "location": { "value": `https://${host}/partners${uri}` } }
        }
        return response;
    }
    
    return request;
}

This function takes the URI path (/aapo) and checks if it does not contain /partner/. If not, the function will :

1. Make the URI path uppercase (/AAPO). Not sure if this is required, but it was upper case in your example.
2. Issue a 302 redirect to the new URL using the same host header as the base host for the URL and adds the /partner/ to the URI path.

If the URI path contains /partner/ the function will return the URL as is (no-op).
