Creating a custom script wrapper for chmod can help you manage and restrict the use of certain chmod commands, such as preventing the setting of 777 permissions. Below is a basic example of how you can create such a script in Ubuntu or any other Linux-based system. Create the Script: You’ll create a script named safe_chmod and place it in a directory like /usr/local/bin which is commonly in the user’s $PATH. Script Content: The script will check for the specific permission pattern (e.g., 777) and display a warning message if that pattern is used. It will execute the normal chmod…

The mod_expires module in Apache is used for controlling the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. These headers determine how long a client (browser or proxy) will cache resources. Optimizing these settings can significantly reduce server load and improve client-side experience by reducing load times. Optimized mod_expires Settings Here’s an optimized mod_expires section for a production server, covering a variety of file types: ## EXPIRES CACHING ## <IfModule mod_expires.c> ExpiresActive On # Default expiration: 1 hour after request ExpiresDefault “now plus 1 hour” # HTML components ExpiresByType text/html…
