Hi!

Quote from wiki:

Add\_header  
“Adds headers to the HTTP response when the response code is equal to  
200, 204, 301, 302 or 304.”

Any reason we missing 206?

I tend to think it was just forgotten, probably because nginx’s  
own range filter (which will generate 206 from 200) only appears  
later in headers filter chain. Therefore nginx’s own 206 will  
have headers added via add\_header, while proxied 206 responses  
won’t.

Trivial patch:
