Let's consider a constant stream of cache requests with a cache capacity of 3, see below:

A, B, C, A, A, A, A, A, A, A, A, A, A, A, B, C, D

If we just consider a Least Recently Used (LRU) cache with a HashMap + doubly linked list implementation with O(1) eviction time and O(1) load time, we would have the following elements cached while processing the caching requests as mentioned above.

[A]
[A, B]
[A, B, C]
[B, C, A] &lt;- a stream of As keeps A at the head of the list.

	A little explanation for those who have no idea what NOBLOGREDIRECT is.

	The define(‘NOBLOGREDIRECT’, ‘%siteurl%’); inside of the wp-config.php makes it so that when someone enters a subdomain that does not exist on your site to redirect to whatever url you wish it to. You can use this to have it either go to a specific FAQ page or directly back to the main root installation, anywhere you want to direct it. the %siteurl% can be replaced for example define(‘NOBLOGREDIRECT’, ‘http://frumph.net/FAQ/site-create’);

	When someone in their browser tries to go to (for example) http://badsubdomain.frumph.net/ a subomain which doesn’t exist, it will go to what is defined in NOBLOGREDIRECT.

	Without using NOBLOGREDIRECT the (for example) http://badsubdomain.frumph.net/ – which is a subdomain that doesn’t exist would direct to the signup page asking which reports whether or not the user can create the bad subdomain in question. This is fine, there’s nothing wrong with it redirecting to the signup page if someone put
