Details

Interwiki caching consists of the following four settings:

$wgInterwikiCache

This setting specifies an array in the following format, or a string with the path to CDB file containing the same keys. 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.

$wgInterwikiScopes  

This setting specifies the number of domains to check for messages:

1. - Just wiki(db)-level
2. - wiki and global levels
3. - site levels

$wgInterwikiFallbackSite  

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.
