Frequently Asked Questions
Common questions about Nginx Helper
Yes, it does. It physically empties the cache directory. It is set by default to /var/run/nginx-cache/.
If your cache directory is different, you can override this in your wp-config.php by adding
define('RT_WP_NGINX_HELPER_CACHE_PATH','/var/run/nginx-cache/');
Replace the path with your own.

Yes. It handles all post-types the same way.
Manually purging any page from the cache, by following instructions in the previous answer.
Version 1.3.4 onwards, Nginx Helper adds a comment at the end of the HTML source ('view source' in your favourite browser):
<!--Cached using Nginx-Helper on 2012-10-08 07:01:45. It took 42 queries executed in 0.280 seconds.-->. This shows the time when the page was last cached. This date/time will be reset whenever this page is purged and refreshed in the cache. Just check this comment before and after a manual purge.
As long as you don't purge the page (or make changes that purge it from the cache), the timestamp will remain as is, even if you keep refreshing the page. This means the page was served from the cache and it's working!
The rest shows you the database queries and time saved on loading this page. (This would have been the additional resource load, if you weren't using fast-cgi-cache.)

Nginx helper plugin handles usual scenarios, when a page in the cache will need purging. For example, when a post is edited or a comment is approved on a post.
To purge a page immediately, follow these instructions:
Let's say we have a page at the following domain: http://yoursite.com/about.
Between the domain name and the rest of the URL, insert '/purge/'.
So, in the above example, the purge URL will be http://yoursite.com/purge/about.
Just open this in a browser and the page will be purged instantly.
Needless to say, this won't work, if you have a page or taxonomy called 'purge'.

Yes, you can force override the redis hostname, port or prefix by defining constant in wp-config.php. For example:
`
define('RT_WP_NGINX_HELPER_REDIS_HOSTNAME', '10.0.0.1');
define('RT_WP_NGINX_HELPER_REDIS_PORT', '6000');
define('RT_WP_NGINX_HELPER_REDIS_PREFIX', 'page-cache:');
`
`
define('RT_WP_NGINX_HELPER_REDIS_HOSTNAME', '10.0.0.1');
define('RT_WP_NGINX_HELPER_REDIS_PORT', '6000');
define('RT_WP_NGINX_HELPER_REDIS_PREFIX', 'page-cache:');
`
Yes, you can force override the redis socket path, username, password by defining constant in wp-config.php. For example:
`php
define( 'RT_WP_NGINX_HELPER_REDIS_UNIX_SOCKET', '/var/run/redis/redis.sock' );
define( 'RT_WP_NGINX_HELPER_REDIS_USERNAME', 'admin' );
`php
define( 'RT_WP_NGINX_HELPER_REDIS_UNIX_SOCKET', '/var/run/redis/redis.sock' );
define( 'RT_WP_NGINX_HELPER_REDIS_USERNAME', 'admin' );
Definitely. WPMU_ACCEL_REDIRECT reduces the load on PHP, but it still ask WordPress i.e. PHP/MySQL to do some work for static files e.g. images in your post. Nginx map lets nginx handle files on its own bypassing wordpress which gives you much better performance without using a CDN.
Most likely yes. A wordpress plugin, if not using explicitly any Apache-only mod, should work on Nginx. Some plugin may need some extra work.
