I\'m trying to use PIE.htc, which is a script which hopefully will allow me to use CSS3 features in IE6-8. I\'m also using Cakephp (which I\'m growing to love)
Accor
I was using CodeIgniter with a mod_rewrite. Based on Septagram's answer I got the following to work
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
#if the url contains PIE.php redirect to the folder containing PIE.php
RewriteCond %{REQUEST_URI} PIE.php$
RewriteRule ^.*$ css3pie/PIE.php [NC,L]
#else just redirect to index
RewriteRule ^.*$ index.php [NC,L]
Hope this helps someone
