Nginx rule – match all paths except one

nginxregex

I am trying to match all paths that begin with /newsletter/ except one (/newsletter/one) with a regex.
What I have so far:

   location ~ ^/newsletter/(.*)$ {
// configuration here
}

This matches all the paths that begin with /newsletter/.

How do I make an exception for the path /newsletter/one ?

I ended up using the following solution:

location ~ ^/newsletter/(.*)$ {
    location ~ /newsletter/one(.*) {
           // logic here
    }
    // logic here
}

This matches all the paths under /newsletter/* and then I match all the paths that begin with /newsletter/one and apply the configuration for the newsletter/one in the inner configuration block while I keep the rest of the configuration in the outer configuration block.

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; 

       [....]
}

NGINX Reverse Proxy – URL Rewrite

Any redirect to localhost doesn't make sense from a remote system (e.g. client's Web browser). So the rewrite flags permanent (301) or redirect (302) are not usable in your case.

Please try following setup using a transparent rewrite rule:

location  /foo {
  rewrite /foo/(.*) /$1  break;
  proxy_pass         http://localhost:3200;
  proxy_redirect     off;
  proxy_set_header   Host $host;
}

Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect.
