To learn how to enable compression on your web server, read this section or start with a sample configuration file. Sometimes compression is available in the settings or when upgrading to a server.
When enabling compression, consider the following:
• Comment votre serveur Web est-il configuré pour mapper les types MIME au contenu ou au fichier?
• How is your web server configured to compress content against these Mimes?
Files and extensions
• How are the file names and extensions in your application structured?
• How does your application change or override the Mime protocol of a response?
• Which third-party libraries use Mime protocols?
Make sure your configuration files are properly implemented across your host network. Next, make sure compression is enabled. In your browser’s management tools, you can search for the header.
When minimizing your files, your main goal is to remove redundant or unnecessary files.
• Comments :
While comments are useful for a designer, they are not necessary for the browser. Delete all comments.
• Spaces (spaces, tabs and line breaks) :
Spaces are also useful for the designer, but the browser does not need them. Remove all unnecessary spaces, tabs and line breaks.
