I'm using `Falcon CORS` to allow access to my web service only from several domains. But it does not work properly.

Let me explain, if we take a look at my implementation:

```
ALLOWED_ORIGINS = ['*']
crossdomain_origin = CORS(allow_origins_list=[ALLOWED_ORIGINS], log_level='DEBUG')

app = falcon.API(middleware=[RequireJSON(), JSONTranslator(), cors.middleware])

```

When I make any post request to my API service, I get this warning:

> 
> Aborting response due to origin not allowed
> 
> 
> 

But, then I get the correct response from my API.  

Here is an official docs about this module: <https://github.com/lwcolton/falcon-cors>
