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

先重現針對 /foo.txt、使用 text/plain 和 text/turtle 的 POST 與 PUT 請求，以及針對 /foo.txt/ 的容器請求。接著檢查相關的 GET 與重新導向行為；當資源 URL 與結尾斜線行為得到一致定義，並且能防止具有相同 URL 的重複資源時，即視為完成。
