POST/PUT in NSS allow multiple resource with same url and different content-type

You can create resources :

1. https://pod/foo.txt with content-type text/plain => creates file : /foo.txt
2. https://pod/foo.txt with content-type text/turtle => creates file /foo.txt$.ttl
3. https://pod/foo.txt/ as a container => creates folder /foo.txt

The first 2 have the same url and there are 2 different files created.
All 3 have the same visual representation in SolidOs.

The first 2 should not occur and I think this is a bug
For the third one I remember @timbl writing it should not occur, but did not find where.
There was also a redirect discussion between foo/bar/ and foo/bar. His this something to do in GET ?

Is there any solid/specification, I did not find anything ? @csarven @michielbdejong

/foo.txt に対する text/plain と text/turtle を使った POST および PUT リクエストと、/foo.txt/ に対するコンテナリクエストをまず再現します。次に、関連する GET とリダイレクトの挙動を調査します。リソース URL と末尾のスラッシュの挙動が一貫して定義され、同じ URL を持つ重複リソースが防止されれば完了です。
