Does Nginx supports If-Range ?

[Nelson Marcos]

Hello everyone!

I don't know if it is an expected behaviour or a bug:


Scenario 1(OK): If I perform a request *with the header Range*,  Nginx
serves the *partial content(HTTP 206)*.

Scenario 2 (NOT OK): If I perform a request *with the header Range AND the
header "If-Range" *with the Etag, Nginx serves the *entire file*(200). Why
not serve the partial content if its cached version matches the If-Range
header?

In both scenarios the file is already cached.

Here is my conf: https://pastebin.com/gQQ0GSg6

Here are my requests and my files: https://pastebin.com/rxLwYaSK


The error happened on my server(Nginx 1.10.2) but I was also able to
reproduce it on my Macbook (nginx 1.12.0).

Thanks for any help :)

Kinds,
NM
