Front-end of our app is not working after migration from Apache to Nginx

Question

This is our config file, we're having problems with the front-end functionality of the app that does work on Apache.

Javascript POST method is not working anymore.

server {

    listen   80;
    server_name website.com www.website.com;
    rewrite ^/(.*) https://website.com/$1 permanent;
}

server {

    listen   443;
    server_name website.com www.website.com;

    root        /usr/share/nginx/www.website.com;
    index index.html index.php;

    # canonicalize codeigniter url end points
    # if your default controller is something other than "welcome" you should change the following
    if ($request_uri ~* ^(/home(/index)?|/index(.php)?)/?$)
    {
            rewrite ^(.*)$ / permanent;
    }

    # removes trailing "index" from all controllers
    if ($request_uri ~* index/?$)
    {
            rewrite ^/(.*)/index/?$ /$1 permanent;
    }

    # removes trailing slashes (prevents SEO duplicate content issues)
    if (!-d $request_filename)
    {
            rewrite ^/(.+)/$ /$1 permanent;
    }

    # removes access to "system" folder, also allows a "System.php" controller
    if ($request_uri ~* ^/system)
    {
            rewrite ^/(.*)$ /index.php?/$1 last;
            break;
    }

    # unless the request is for a valid file (image, js, css, etc.), send to bootstrap
    if (!-e $request_filename)
    {
            rewrite ^/(.*)$ /index.php?/$1 last;
          break;
    }

            auth_basic_user_file  /etc/nginx/htpasswd;
    }

    location ~* \.php$ {
            fastcgi_pass 127.0.0.1:9000;

            include fastcgi_params;

    # PHP only, required if PHP was built with --enable-force-cgi-redirect
            fastcgi_param   REDIRECT_STATUS         200;
            fastcgi_param SCRIPT_FILENAME /usr/share/nginx/www.website.com$fastcgi_script_name;
    }

    location ~ /\.ht
{
    deny all;
  }

  }

Answer:

I finally know what went wrong and how to fix it. The config of nginx should only apply to static JS, not to the PHP actions.

Configure this:

location ~ ^/(assets)/ {
  expires max;
  break;
 }

Replace "assets" with "js" and it will work.

Answer 1

Your (permanent) rewrite rule will return a 301 redirect for every request - including POSTs. So any post vars will be lost
