HTTP Response Header for static content

The image is an example of the http node.
Here you have to do it in the settings file by combining Steve's message and mine

httpStatic: [
    {
            path: '/home/username/.node-red/node-red-static/',
            root: '/static/',
            middleware: function (req, res, next) {
                const ext = path.extname(req.url);

                // Check if the request is for JPG or PNG images
                if (ext === '.jpg' || ext === '.png') {
                    // Set Cache-Control header for images
                    res.setHeader('Cache-Control', 'public, max-age=86400');
                }

                // Continue to the next middleware
                next();
            }
    }
]

Like Steve said, it's not sure to work
