Hi,
First of all, you need to configure Memcached daemon. In the config
file you showed, it is located at localhost:10000 .
So when a client visit your site, nginx will try this Memcached server
to fetch the key defined in $memcached_key. If the client requests
domain1.com/path1/file1.php
This URL would be the key in Memcached cache, that stores the HTML
cache file for that page.
If nginx cannot find the key in the Memcached cache, it will return an
404 error, which in the config file will fallback to the backend
proxy.
The first time when a visitor views the page, it will always fallback
to the backend. At that time, you should add in your PHP code to store
the HTML page in the Memcached with the correct key. So the next time,
the page will be served by nginx using the contents in the Memcached
cache.
Does it make sense? For PHP memcached client, you can use the official
php-memcache module.
