We are trying to forward some arabic character in the uri. The flow of request is :-

Nginx (Proxy) -> Tomcat Banckend

The url is something likeحـرآمے^_^بـنـآت.
Now in the output of the nginx log I am getting something like this :- - - [14/Sep/2015:12:12:24 +0000]"PUT /v1/test/%D8%AD%D9%80%D8%B1%D8%A2%D9%85%DB%92%5E_%5E%D8%A8%D9%80%D9%86%D9%80%D8%A2%D8%AA HTTP/1.1" 405 568 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.85 Safari/537.36" - Time: 0.169

In the backend tomcat the logs is something like this :-

SEVERE: Servlet.service() for servlet CXFServlet threw exception
java.lang.IllegalArgumentException: Illegal character in path at index 53: http://badges_cluster/badges-service-web/v1/badge/حـرآÙ

And in the response code it throws a 500 exception. The applicaiton is not able to understand the request as they are all junk charcters for it. Now we have enabled utf-8 character encoding in the nginx.conf

http {

include /etc/nginx/mime.types;
charset utf-8;

access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

ignore_invalid_headers on;

# client_header_timeout 1;

client_header_timeout 10;

# client_body_timeout 2;

client_body_timeout 10;
server_tokens off;
sendfile on;
tcp_nodelay on;
tcp_nopush on;

# keepalive_timeout 0;

keepalive_timeout 0;

gzip on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

But still doesn't help.

From the report it looks like the problem is that backend is unable to handle the request, not nginx. It doesn't looks like a bug in nginx.

Note that this Trac is to track bugs in nginx, not to ask for help with nginx configuration. If you need help, consider asking in the mailing list instead.

Note: See TracTickets for help on using tickets.
