I want to have case insensitive URLs using Apache\'s mod_speling
module, but this is producing unwanted lists of \"multiple options\" whilst the Apache documention
After reading user1647075's answer about this being a known Apache bug that's unlikely to be fixed, I decided my best option was to hide the "multiple options" page from the user by updating my Apache config to show the 404 error page for 300 status codes:
ErrorDocument 300 /404.htm
Of course, you can also create a custom error page instead of reusing the 404 error page.
Hope this workaround helps.
