Loading external plugins from local machine

Hi i had a plugin in my local machine and i try to integration it in existing build using the following code

external_plugins: {
    'eqneditor':'file:///Users/varun.meka/Desktop/tiny_mce_v3.5.8⁩/plugins⁩/equation⁩/editor_plugin.js'
  },

but it’s not loading

You can run a simple http server on you local machine and use that address.

Not without changing the plugin, I’m afraid.
