Port redirection is not working as expected in nginx reverse proxy

Here is one more issue I am facing. I have portal running on http://test.example.com:8080/AppWise and http://test.example.com/WebAdmin

Now I diverted that portal through Nginx reverse proxy

here is my config

server {
    listen 8080;
    listen 80;
    server_name test.example.com;
    access_log /var/log/nginx/twprod/access.log;
    error_log /var/log/nginx/twprod/error.log;
    include /etc/nginx/applox/feeds/badips.txt;
    location /AppWise/ {
        client_max_body_size 10m;
        client_body_buffer_size 128k;
        proxy_send_timeout 90;
        proxy_read_timeout 90;
        proxy_buffer_size 128k;
        proxy_buffers 4 256k;
        proxy_busy_buffers_size 256k;
        proxy_temp_file_write_size 256k;
        proxy_connect_timeout 30s;
        proxy_pass http://test.example.com:8080;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
    location /WebAdmin/ {
        client_max_body_size 10m;
        client_body_buffer_size 128k;
        proxy_send_timeout 90;
        proxy_read_timeout 90;
        proxy_buffer_size 128k;
        proxy_buffers 4 256k;
        proxy_busy_buffers_size 256k;
        proxy_temp_file_write_size 256k;
        proxy_connect_timeout 30s;
        proxy_pass http://test.example.com:8080;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

The thing is First page open properly and then it asks for username password; this is fine. now after login suddenly I receive 302 and page is diverted to http://test/example.com/Appwise/<...........REST of the URI.....>

I expected for this page to stay at http://test.example.com:8080
