Nginx Redirecting from file list

configurationnginxredirect

I would like nginx to perform redirects (302) on certain urls while changing part of the url to another based on a file (lets say a csv). For example:

https://localhost/foo/100/bar.html to redirect to https://localhost/foo/209/bar.html

https://localhost/foo/102/bar.html to redirect to https://localhost/foo/1000/bar.html

https://localhost/foo/99/bar.html doesn't redirect

Because the file(lets say again csv) has the lines:

"old";"new"
100; 209
101; 203
102; 1000
...

Is it possible without an application server (proxy pass)?

Not that I know of, not from CSV. You need to list your redirects manually.

location https://localhost/foo/100/bar.html {
    return 301 https://localhost/foo/209/bar.html;
}
location https://localhost/foo/102/bar.html {
    return 301 https://localhost/foo/1000/bar.html;
}

However you could try the technique suggested in this SF post, using Maps. It's not CSV but it's easier than manual maintenance of redirect rules.

Turn out my first answer to this question was correct at certain time, but it turned into another pitfall - to stay up to date please check Taxing rewrite pitfalls

I have been corrected by many SE users, so the credit goes to them, but more importantly, here is the correct code:

server {
       listen         80;
       server_name    my.domain.com;
       return         301 https://$server_name$request_uri;
}

server {
       listen         443 ssl;
       server_name    my.domain.com;
       # add Strict-Transport-Security to prevent man in the middle attacks
       add_header Strict-Transport-Security "max-age=31536000" always; 

       [....]
}

Ssl – When Using Reverse Proxy, Backend Server Does 301 Back to The Proxy Server or Changes URL

I have done that by the following code. You can try it...

    ProxyPreserveHost On
    <Proxy *>
            AddDefaultCharset off
            Order deny,allow
            Deny from all
          Allow from all
    </Proxy>

            ProxyPass /google http://www.google.com/
            ProxyHTMLURLMap http://www.google.com /google

    <Location /google>
            ProxyPassReverse /
            ProxyHTMLInterp On
            ProxyHTMLURLMap  /      /google
            RequestHeader    unset  Accept-Encoding
    </Location>
