sails.js: how to disable etags

I read this not very new post about disabling some things in sails.js. Specifically what I would like to try out is the disabling of etags.

Does anyone know how to disable that in sails.js (0.11.0)?

The above answer is only for dynamic files. For static files, you must override the www middleware by adding this code to the config/https.js file

www: (function() {
  var flatFileMiddleware = require('serve-static')('.tmp/public', {
    maxAge: 31557600000,
    etag: false
  });

  return flatFileMiddleware;
})(),

The maxAge has to be there if you still want to set the cache-control header with an age. Also note that this will override the cache option in the same http.js file used to define that age.

For my purpose, I only wanted to remove the etags from the static files served up in the /min folder, which are the minified css and js files. So to do this I had to define a route in the routes.js file

'get /min/*': { 
  skipAssets: false,
  fn: [
    require('serve-static')('.tmp/public', {
      maxAge: process.env.NODE_ENV !== 'production' ? 0 : 31557600000,
      etag: false
    }),
  ]
}

You could disable it in the bootstap.js file:

// config/bootstrap.js
module.exports.bootstrap = function(cb) {

  // Add this line to access to the Express app and disable etags
  sails.hooks.http.app.disable('etag');

  // It's very important to trigger this callback method when you are finished
  // with the bootstrap!  (otherwise your server will never lift, since it's waiting on the bootstrap)
  cb();
};
