Hello All,

I have erlang web application with cowboy web server and i launched it  
behind nginx reverse proxy.

My nginx configuration:

server {  
listen 9090;

location /test {  
proxy\_pass [http://localhost:8080](http://localhost:8080);  
proxy\_http\_version 1.1;  
}  
}

Where [http://localhost:8080](http://localhost:8080) is my cowboy web server. When i’m openning:  
[http://localhost:8080/test](http://localhost:8080/test) i see my html page, it’s ok,

Browser shows response headers:

Transfer-Encoding:chunked

Server:nginx/1.2.6 (Ubuntu)

Content-Type:text/html

Content-Encoding:gzip

Connection:keep-alive

It’s normal, but… I see the following string right on the my html  
page:

“HTTP/1.1 204 No Content connection: close server: Cowboy  
content-length: 0”

Why nginx adds this string with headers to the html page? And it occurs  
only if i set up Content-Type: text/html header.

Thank you.

Looks like your backend returns malformed response for some  
reason. You may try digging further into what your backend  
returns.
