Nginx: redirect from old url to new one and keep query string

nginxrewrite

I need to rewrite old urls to new ones using nginx rewrite. I have one problem with query string. Redirection does not work if old url has query string parameter. My current config:

map $request_uri $newuri {
    /old-url/path /new-url/path;
}

server {
    location / {
        if ($newuri) {
            return 301 $newuri;
        }
    }
}

Your map statement is performing a string match on $request_uri. The variable $request_uri also includes the query string. If you want to match with and without the query string, you should match only the front of $request_uri, which can be accomplished using regular expression syntax:

map $request_uri $newuri {
    ~*^/old-url/path /new-url/path;
}

See this document for details.

Nginx rewrite rule to convert URL segments to query string parameters

Disclaimer: None of the following are tested. Please use it with caution. If anything goes wrong, please turn on debugging as mentioned at http://nginx.org/en/docs/debugging_log.html .

See if it's a real file or directory, if so, serve it,
then send all requests for / to Director.php

This may be achieved with...

server {
  index Directory.php;
  location / {
    try_files $uri $uri/ /Directory.php;
  }
}

The index directive is enough for directory index. To send all requests to Director.php, then location block is needed.

If the URL has one segment, pass it as rt

You may try the following...

rewrite "^/([a-zA-Z0-9\-\_]+)/$" "/Director.php?rt=$1" last;

Please remember the quotes around the rewrites. It is preferable to use quotes, and is needed on certain conditions (that is mentioned in the link provided earlier by @jerm).

If the URL has two segments, pass it as rt and action

You may try the following...

rewrite "^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$" "/Director.php?rt=$1&action=$2" last;

Please note that I haven't done anything for QSA in the above examples. You may try $args variable in Nginx to pass the existing query string to the new query string. Ref: http://nginx.org/en/docs/http/ngx_http_core_module.html#variables

I hope that helps to arrive at the full working solution!

Nginx – Redirect via Proxy, Rewrite and Preserve URL

First, you shouldn't use root directive inside the location block, it is a bad practice. In this case it doesn't matter though.

Try adding a second location block:

location ~ /some/path/(?<section>.+)/index.html {
    proxy_pass http://192.168.1.24/$section/index.html;
    proxy_set_header Host $host;
}

This captures the part after /some/path/ and before index.html to a $section variable, which is then used to set the proxy_pass destination. You can make the regex more specific if you require.
