I blogged about some of the issues involving IIS and case folding over on SEOmoz. Some interesting suggestions.
Best comment so far from “G-Force”, to embed some ASP code in each page that checks the file name, and 301′s to the “right” case variant. Heavy work – individual page edit for each unique page. Unless, hmm, one uses one of the Unix tool kits. I could see using Perl to auto edit each file in a directory hierarchy.
