nginx and upstream prematurely closed connection while reading upstream

[wilk]

Hi,

I'm experiencing a lot of log in nginx :
upstream prematurely closed connection while reading upstream

Looking in my code it's because I added

w.Header().Set("content-length", strconv.Itoa(len(w.Body.Bytes())))
If i remove it, no more logs and my clients are happy again

I use an httptest.ResponseRecorder as a response buffer.

then write the headers (content type and cookies), write the code and
write the body wrt.Write(w.Body.Bytes()). Nothing special, if i look
with curl the content-lenght seems to be ok.

I don't see where i did a mistake, and it's difficult to find because
i cannot reproduce it localy.

Thanks
