Content-Type header not proxied to downstream hosts

December 10, 2014 09:47PM
Hi,

I'm new to nginx so am probably making a simple mistake but, for the life of me, I can't see what.

I want to proxy requests with all headers that the request had to a downstream server if it matches a regex. I also have an issue with the regex, but let's leave that for another post.

The nginx conf is very simple. I know the request sent to nginx contains the Content-Type header with value application/json from the access log:

Format:

$remote_addr - $remote_user [$time_local] "$request" $sent_http_content_type ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'

Output:

127.0.0.1 - - [10/Dec/2014:18:34:49 -0800] "GET /event/3F0046E6B50F75A8/info HTTP/1.1" application/json 200 532 "-" "Apache-HttpClient/4.3.5 (java 1.5)" "-"

However, the downstream host doesn't receive it. All other headers, including custom headers, are sent.

My nginx config is basic, see this gist:

https://gist.github.com/mikquinlan/e68848bb4930725a6fdd

I have a workaround by manually adding the header, but I shouldn't have to do it:

proxy_set_header Content-Type application/json;

I get the same result using nginx 1.4.4 and 1.6.2.

nginx -V output is below.

Any ideas what I'm doing wrong?

All help appreciated.

Mik
