Hello,

I am making a byte range request to NGINX using wget. NGINX responds with status code 206 (partial content), but instead of downloading the content, wget retries.

Request:

wget -S 'http://cache.example.com/video5.ts' --header="Range: bytes=0-1023"

Output from wget:

--2019-08-02 15:36:44-- http://cache.example.com/video5.ts
Resolving cache.example.com (cache.example.com)... 172.16.200.5
Connecting to cache.example.com (cache.example.com)|172.16.200.5|:80... connected.
HTTP request sent, awaiting response...
HTTP/1.1 206 Partial Content

Retrying.

Then wget sends the request again, with the same result.

The same wget request to the origin succeeds. The data is cached properly (wget without the range header succeeds).

Adding —debug to the wget provides not much more.

Registered socket 3 for persistent reuse.
Disabling further reuse of socket 3.
Closed fd 3
Retrying.

There is nothing in the NGINX error log.

I am speculating that NGINX closes the connection before the data is delivered. But why?

Thanks…

Roger
