Fingerprinting

[3rd-Eden]

Fingerprinting is a technique that transforms the filename in the HASH of the content, so when the contents of a file changes the file name changes as well. This allows you to set far future caching headers and when you update the contents of your file, a new file will be cached. So there is no need for version management.

Fingerprinting should be enabled by default. When you create a new file we should add the original file path to a list of aliases. So we can lookup the file paths and get the new name and URL location of the asset.

var Factory = require('sfs')
   , sfs = new Factory()
  , File = sfs.File;

y = new File(path);

sfs.get(path, function (err, paths) {
  /* paths should be an array */
});
