Interwiki caching consists of the following three settings:

This setting specifies an array in the following format. This format can be generated with dumpInterwiki.php .
  • dbname:key - a simple key (e.g. enwiki:meta)
  • _sitename:key - site-scope key (e.g. wiktionary:meta)
  • __global:key - global-scope key (e.g. __global:meta)
  • __sites:dbname - site mapping (e.g. __sites:enwiki)
Sites mapping just specifies site name, other keys provide "local url" data layout.
This setting specifies the number of domains to check for messages:
  1. - Just wiki(db)-level
  2. - wiki and global levels
  3. - site levels
This setting is used if unable to resolve from the cache.

Since 1.19 it is possible to get the list of cached interwiki prefixes, used in the API and Extension:Interwiki extension.
