Magento – Magento wrongly redirects https!

I've posted a working sample config below. Included is a set of rewrite rules that allows us to serve up static html pages from the "static" directory. If we're advertising a product like http://yourdomain.com/super-popular.html that we expect many thousands of concurrent hits to, we may opt to save the html of super-popular.html in the static directory to skip php entirely. Nginx absolutely crushes Apache in serving up these pages in particular.

We've experienced rock solid performance with the config below.

server {
    listen 80 default ;
    server_name www.yourdomain.com;
    root /var/www/production/web;

    ## allow for html source of super high volume product pages to be put in "static" directory and served without php
    if ($http_host ~ "^(.*)yourdomain.com"){
        set $rule_0 1;
    }
    if ($uri ~ "^(.*)$"){
        set $rule_0 2$rule_0;
    }
    if ($http_referer !~* ".*yourdomain.com"){
        set $rule_0 3$rule_0;
    }
    if (-f $document_root/static$request_uri){
        set $rule_0 4$rule_0;
    }
    if ($rule_0 = "4321"){
        rewrite ^/.*$ /static/$request_uri last;
    }

    ## Images and static content is treated different
    location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ {
            access_log        off;
            expires           30d;
            root /var/www/production/web/;
    }

    location / {
        index index.html index.php; ## Allow a static html file to be shown first
        try_files $uri $uri/ @handler; ## If missing pass the URI to Magento's front handler
        expires 30d; ## Assume all files are cachable
    }

    ## These locations would be hidden by .htaccess normally
    location /app/                { deny all; }
    location /includes/           { deny all; }
    location /lib/                { deny all; }
    location /media/downloadable/ { deny all; }
    location /pkginfo/            { deny all; }
    location /report/config.xml   { deny all; }
    location /var/                { deny all; }
    location /nginx-config/       { deny all; }

    location  /. { ## Disable .htaccess and other hidden files
        return 404;
    }

    location @handler { ## Magento uses a common front handler
        rewrite / /index.php;
    }

    location ~ .php/ { ## Forward paths like /js/index.php/x.js to relevant handler
        rewrite ^(.*.php)/ $1 last;
    }

    location ~ .php$ { ## Execute PHP scripts
        if (!-e $request_filename) { rewrite / /index.php last; } ## Catch 404s that try_files miss

        expires        off; ## Do not cache dynamic content
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_read_timeout 120;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param  MAGE_RUN_CODE yourdomain_store;
        fastcgi_param  MAGE_RUN_TYPE store;

        include        fastcgi_params; ## See /etc/nginx/fastcgi_params
    }

  access_log /var/log/nginx/yourdomain.com-access_log combined;
}

@handler is missing in your config. Try the following config. Update root and fastcgi_pass according to your environment.

server {   
    listen      x.xxx.xxx.x:80;
    server_name domain.es www.domain.es;

    root /home/user/web/domain.es/public_html;
    index index.php;
    location = /js/index.php/x.js {
        rewrite ^(.*\.php)/ $1 last;
    }

    ## Main Magento @location
    location / {
       try_files $uri $uri/ /index.php?$args;
    }


    ## These locations are protected
    location ~ /(app|var|downloader|includes|pkginfo)/ {
        deny all;
    }

    ## Images
    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        expires max;
        log_not_found off;
        access_log off;
        add_header ETag "";
    }

    ## Fonts
    location ~* \.(swf|eot|ttf|otf|woff|woff2)$ {
        expires max;
        log_not_found off;
        access_log off;
        add_header ETag "";
        add_header Access-Control-Allow-Origin "*";
        add_header Cache-Control "public";
    }


    ## Execute PHP scripts
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass    127.0.0.1:9002;
        fastcgi_buffers 1024 4k;

        fastcgi_param  PHP_FLAG  "session.auto_start=off \n suhosin.session.cryptua=off";
        fastcgi_param  PHP_VALUE "memory_limit=768M \n max_execution_time=600";
        fastcgi_read_timeout 600s;
        fastcgi_connect_timeout 600s;

        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;

    }
