I wrote a new ikiwiki plugin (download source) to generate redirection files so that the URL http://example.com/wiki/foo.html turns into http://example.com/wiki/foo/.

This plugin is particularly useful when converting old sites built with static wiki pages into shiny new ikiwiki ones, while preserving external links.

I'm happy to contribute the module to ikiwiki if there's interest.  Source is [here](
