Redirecting to non-clean URLs?

**Please describe which feature you have a question about?**

Rewrites/redirects that result in non-clean URLs.

I have failed to figure it out reading , and , and by browsing the issues here.

**Provide additional details**

I am trying to redirect to a site that does not use clean URLs, and so I want to transform the path from `//` or `/` to `/.html`.

**What AWS Services are you utilizing?**

AWS Amplify

**Provide additional details e.g. code snippets**

My current **Rewrites and redirects** configuration is:

```json
[
{
"source": "https://master.dhfqby5l2aw43.amplifyapp.com/2019/10/21/beta",
"target": "https://qa-backstage.forgerock.com/docs/sdks/latest/2019/10/21/beta.html",
"status": "301",
"condition": null
},
{
"source": "https://master.dhfqby5l2aw43.amplifyapp.com",
"target": "https://qa-backstage.forgerock.com/docs/sdks/latest",
"status": "301",
"condition": null
}
]
```

When I `curl` the first URL, I would expect to get `location: https://qa-backstage.forgerock.com/docs/sdks/latest/2019/10/21/beta.html`, but instead I get `location: https://qa-backstage.forgerock.com/docs/sdks/latest/2019/10/21/beta`. Notice that the `.html` extension is missing.

```
curl -I https://master.dhfqby5l2aw43.amplifyapp.com/2019/10/21/beta
HTTP/2 301
content-length: 0
location: https://qa-backstage.forgerock.com/docs/sdks/latest/2019/10/21/beta

Start with the AWS Amplify redirects documentation and the linked FAQ, then reproduce the reported behavior using the supplied curl command and redirect configuration. Determine whether Amplify can preserve the .html suffix in the Location header; done means documenting the supported configuration or confirming the platform limitation.
