Case insensitive URL Redirect

[Rob832]

Looking for a better way to setup a case insensitive URL redirect such that if user types
www.mysite.com/SPEEDmachine
it redirects them to
www.mysite.com/speed-machine-part-1/

I have the following brute force rules setup in .htaccess and these work fine:

RewriteEngine On
RedirectMatch /speedmachine http://www.mysite.com/speed-machine-part-1/
RedirectMatch /SpeedMachine http://www.mysite.com/speed-machine-part-1/
RedirectMatch /SPEEDMACHINE http://www.mysite.com/speed-machine-part-1/

However, the above rules fail for a different capitalization mix, such as: mysite.com/SpEEdMachinE

I tried the cPanel URL Redirect app, however it only handles the specific URL capitalization as I type it:
RewriteCond %{HTTP_HOST} ^mysite.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.mysite.com$
RewriteRule ^speedmachine\/?$ "http\:\/\/www\.mysite\.com\speed\-machine\-part\-1\/\/" [R=301,L]

I tried adding NC flag to the [R=301,L] options, for example
[R=301,L,NC]
but this has no affect and a mixed case URL doesn't redirect.

Appreciate your help.

Try this method, but heed the warning. I would limit the rule to just the letters you need. Found with a google search on rewriterule lowercase.

I'm not too good with htaccess, would this work or would it be too cumbersome:

have a rule to extract the page value (SpEEdMachinE)
using php convert the value to all lowercase (speedmachine)
attach it to your web address (http://www.mysite.com/speedmachine)
load a it as a new page.

Use a php file as your 404 page that looks through the directory for similarly named files.
