Manual:Externallinks table/ja

externallinks テーブル はMediaWiki が外部リンクを記録し、追跡する場所です. このテーブルは 1.5 の後に導入されました.

el_from
The page identifier of the referring wiki page.

el_to
The actual URL itself. It is passed to the browser.

el_index
This is the same URL as  search-optimised: username and password information is stripped, and the other components are reversed for faster searching, so  http://user:password@sub.example.com/page.html  becomes  http://com.example.sub./page.html , which allows searches of the form 'Show all links pointing to *.example.com'.
