Kong dropping some of the request headers

[tejas3190]

As observed from Wireshark, Kong is not forwarding all the headers to upstream.
I am trying to send a request with following headers.

1. "com.bea.wlcp.wlng.plugin.sms.RequestDeliveryReportFlag":"true"
2. "test": "ok"

At the upstream server "com.bea.wlcp.wlng.plugin.sms.RequestDeliveryReportFlag":"true" is not coming. Does kong has any limitation ?

• Kong version (0.13.1)

I suppose you also get something like this in error.log:

2018/07/03 17:12:42 [info] 3562#796588: *782 client sent invalid header line: "com.bea.wlcp.wlng.plugin.sms.RequestDeliveryReportFlag: true" while reading client request headers, client: 127.0.0.1, server: kong, request: "GET / HTTP/1.1", host: "kong.test:8000"

Kong by default uses a lot of Nginx defaults. If you need to change this, you need to have this:
http://nginx.org/en/docs/http/ngx_http_core_module.html#ignore_invalid_headers

set to:

ignore_invalid_headers off;

As this is Nginx configuration setting, and we are using the default, I feel this is more like a configuration issue on your side, so I will close this.

This will come with 0.14.0:
#3530

So you don't even need to use custom nginx configuration there anymore to change this.

Thanks you are right
