HTTP Get with 204 No Content: Is that normal

Question

Is it a normal occurrence for an HTTP GET Request to have a response with status code 204 - No Content? Like, is this semantically correct concerni

Answer 1

I use GET/204 with a RESTful collection that is a positional array of known fixed length but with holes.

GET /items
    200: ["a", "b", null]

GET /items/0
    200: "a"

GET /items/1
    200: "b"

GET /items/2
    204:

GET /items/3
    404: Not Found
