What are the potential drawbacks of automatically converting folder names to lowercase in URLs?

Automatically converting folder names to lowercase in URLs can potentially lead to issues with case-sensitive file systems or servers. This can result in broken links or missing resources if the actual folder names do not match the lowercase version used in the URLs. To solve this issue, you can modify the URL rewriting rules to preserve the original case of folder names when constructing URLs.

// Original URL rewriting rule
RewriteRule ^([a-z0-9-]+)/?$ index.php?page=$1 [L]

// Updated URL rewriting rule to preserve case of folder names
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?page=$1 [QSA,L]
