Are there any best practices for optimizing the performance of mod_rewrite rules in PHP?

When using mod_rewrite rules in PHP, it is important to optimize their performance to ensure efficient redirection of URLs. One best practice is to use the [L] flag at the end of each rule to stop processing further rules if a match is found. Additionally, organizing rules from most specific to least specific can improve performance by reducing the number of rules that need to be evaluated.

RewriteEngine On

# Redirect specific URLs
RewriteRule ^about$ about.php [L]
RewriteRule ^contact$ contact.php [L]

# Redirect all other URLs to index.php
RewriteRule ^(.*)$ index.php [L]
