Nginx Cache Controller Plugin

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
