This is a preserved training example. Membership in the current training wave has not been verified.

Problem statement

Query Params - difference between API GW and ALB
I noticed if I go to a URL with a query string like this: `?x=foo%3Dbar`

The event sent to a lambda from ALB contains:
```json
"queryStringParameters":  {
    "x": "foo%3Dbar"
}
```

And the event sent from API Gateway contains:
```json
"queryStringParameters":  {
    "x": "foo=bar"
}
```

For the ALB, the QUERY_STRING in the WSGI environment is set to:
```
x=foo%253Dbar
```

And for API Gateway, it is set to:
```
x=foo%3Dbar
```

So I think the processing of query params for ALB needs to not urlencode the data.

I am working on a PR for this and will hopefully submit later today.
