NGINX rewrite rule changes URL

Question

Nginx rewrite rule changes URL in browser. I saw this one question with the same problem, but it does not help me.

Nginx version:

# nginx -v
nginx version: nginx/1.10.1

Here is my configuration:

And i expect in browser to see: http://servername/something but instead of this i see http://servername/wps/portal/Home/something/. What i do:

1. Save original URI and place it in header

   set $original_uri $request_uri; proxy_set_header X-Rewrite-URL $original_uri;

2. Set X-Rewrite-URL as $request_uri before and after rewrite

   proxy_set_header X-Rewrite-URL $request_uri;

Same configuration in Apache works perfectly:

RewriteEngine on
RewriteRule ^/something\/*$ /wps/portal/something [L,PT] 

UPDATE #1: I try to do it using location and proxy pass

location / {
    ....
    location /opendata {
        proxy_pass http://localhost:8888/wps/portal/Home/opendata/;
    }
    ....
}

It does not help me too

Answer 1

The proxy_pass directive can handle this case.Note that the comment from @richard-smith is also correct, which leads me to think that perhaps your instance is not fully reloading between configuration changes or there is something missing from your problem description.
