Answer 1

You need to define a rewrite map which can only be done in server/vhost config files, not in htaccess files. You'll need to add something like:

RewriteMap lc int:tolower

Then in your htaccess file, you can create a rule like:

RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule ^(.*\.aspx)$ ${lc:$1} [L,NC]

This will check that there are capital letters in the URI, then apply the map which turns everything into lowercase letters.
