Purge is a function that is sometimes necessary to use to update a wiki page whenever template- or subpage-transclusions are involved. Purging clears the page's server cache, and the page is rebuilt. Before purging, you may want to try first to refresh the page using your web browser.
A block of memory cannot necessarily be placed at an arbitrary location in the cache; it may be restricted to a particular cache line or a set of cache lines [1] by the cache's placement policy. [2] [3] There are three different policies available for placement of a memory block in the cache: direct-mapped, fully associative, and set-associative.
The response provided by a cache is stale (the content's age exceeds a maximum age set by a Cache-Control header or heuristically chosen lifetime). 111 Revalidation Failed The cache was unable to validate the response, due to an inability to reach the origin server. 112 Disconnected Operation
When a cache line is reused the RRPV is set to zero, indicating that the line has been reused once and is likely to be reused again. On a cache miss, the line with an RRPV equal to the maximum possible RRPV is evicted; with 3-bit values, a line with an RRPV of 2 3 - 1 = 7 is evicted. If no lines have this value, all RRPVs in the set are ...
It failed for complicated reasons, has limped along unmaintained since 2016-ish, and is currently in the process of being completely removed now that DiscussionTools was deployed as the outcome of the 2019 talk pages consultation.

Diagram of a CPU memory cache operation. In computing, a cache (/ k æ ʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.
