Hi all,

I am trying to make a dynamic reverse proxy which proxies the local
webservers on different ports

I try doing this way :

#user  nobody;
worker_processes  1;

#pid        logs/nginx.pid;

events {
    worker_connections  1024;

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

server {
     server_name  _;
     access_log  /var/log/nginx/proxy.access.log;

     location /
     set $rd_port  $arg_port;
     proxy_set_header        Host    $proxy_host;


        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;

So when the page is requested using eg.
., it will redirect to http service running on 12345 . It work as expect
but only for one dynamic page / requested page, If that page have source
other static contents from its own it fails .

So to be make it possible need to put ?port=12345 on every links ,
images , etc.

How can i make it work as normally ?
