html files without the .html extension

[Andrei Alexandrescu via Digitalmars-d]

To my surprise I saw that all pages linked from 
http://dlang.org/spec.html do NOT have an .html extension, see e.g.

http://dlang.org/intro
which Just Works(tm). However, it doesn't work when I test the site 
locally or upload it for testing on my own website.

Do we have some automatic extensionless to .html name conversion going 
on dlang.org that I've been missing?


Thanks,

Andrei
