Provides some functions of controlling Nginx proxy server cache.

== Description ==

This plugin provides some functions of controlling Nginx proxy server cache.

= Security =

* Making comment authors' information ajaxed to prevent the information from caching.
* Send no-cache header on password protected posts to prevent the posts from caching.
* When a scheduled post is published, it will delete the cache through Ajax.

= Controlling cache =

* Sending X-ACCEL-EXPIRES, you can specify the available period of the cache.
* When you save your post and someone post comments, the cache is deleted automatically.
* Add a menu on the admin bar to delete the cache.

= Memo =

* Gets comment poster's IP address by HTTP_X_FORWARDED_FOR header.
* Fixes the issue that the permanent link setting includes index.php.
* When the cache's expiration period is more than 86400 sec, change the value of wp_verify_nonce() same as the period.

= WP-CLI Support =

Flush all proxy caches.
`wp nginx flush`

Show list of all proxy caches.
`wp nginx list --format=csv`

`wp nginx list --format=json`

See help.
`wp help nginx`

== Installation ==

* A plug-in installation screen is displayed on the WordPress admin panel.
* It installs it in `wp-content/plugins`.
* The plug-in is made effective.

Example of Nginx settings:

Allow X-ACCEL-EXPIRES for fastcgi.

`   location ~ \.php$ {
        include        /etc/nginx/fastcgi_params;
        fastcgi_pass   unix:/tmp/php-fpm.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $vhost_root/$fastcgi_script_name;
        fastcgi_pass_header "X-Accel-Redirect";
        fastcgi_pass_header "X-Accel-Expires";
    }`

Setting cache directory for reverse proxy.

`proxy_cache_path  /var/cache/nginx levels=1:2 keys_zone=czone:4m max_size=50m inactive=120m;`

* The default path is /var/cache/nginx.
* The default value of levels is 1:2.
* You can change the cache path at the admin panel.

Setting the key for the reverse cache proxy.

`proxy_cache_key "$scheme://$host$request_uri"`

* You can customize proxy_cache_key with `nginxchampuru_get_reverse_proxy_key` hook.
