Can you give us some research on your proclaimed less is more just due to the fact that it was built (robot.txt) to do what the webmaster needs. The example given was looks to be a little long and could be combined. However adding Cloudflare in front can also be bad due to the extra hops it takes this slowing down your side until the request reaches your server fromThat's a bit overkill for a list. Also if you block them with cloudflare it works better as you use their resources to block the bot instead of the bots using your stuff to initiate the block. The general rule of thumb for a .htaccess is, the less in it, the better. You just gave us a pretty good sample of what not to do to a .htaccess.
General well known tips for optimizing .htaccess performance:
- Minimize the number of directives: Only include essential configurations in your .htaccess file.
- Consider server configuration: If you have access to the main server configuration file ( httpd.conf ), it's generally recommended to place directives there for better performance, as it is parsed less frequently.
- Combine directives: When possible, combine multiple directives into a single line to reduce parsing overhead.
