What if, for
some reason, [[ADSL]] would be changed to redirect to
another page, or become a disambiguation page rather than a redirect?
All those links to [[ADSL]] would then link to the wrong page.
Presumably it would be done when the page is parsed just before being
viewed, rather than when it's saved. I guess it would be done at the
same time as the existence of the article is checked in order to make
the link blue or red.
That happens when the page is edited or purged. Do edits to A cause a
purge on B if B links to A?
