DirectURL setting in configuration.js won't apply after modified

[SAW4]

As mentioned by author, DircetURL's setting should be set in the file configuration.js then webUI will read it
But after many times I tried, its not worked as expected.
Finally I found a temporary solution, in js/services/rpc/rpc.js :

...
  var subscriptions = []
    , configurations = [authconf]
    , currentConf = {}
    , currentToken
    , timeout = null
    , forceNextUpdate = false;

  var cookieConf = utils.getCookie('aria2conf');
  // try at the start, so that it is presistant even when default authconf works
  if(cookieConf) configurations.unshift(cookieConf);
  if (['http', 'https'].indexOf(uri.protocol()) != -1 && uri.host() != 'localhost') {
    configurations.push({
      host: uri.host(),
      path: '/jsonrpc',
      port: 6800,
      encrypt: false,
      directURL: 'http://core:81/data_drive/'     // To add this line, as your DirectURL
    },
    {
      host: uri.host(),
      port: uri.port(),
      path: '/jsonrpc',
      encrypt: ( uri.protocol() == 'https' )
    },
    {
      host: uri.host(),
      port: uri.port(),
      path: authconf.path,
      encrypt: ( uri.protocol() == 'https' )
    });
  }
...

After changing, you may need to clear the cookies. Then every time you visit aria2-webUI (even refresh the page, restart aria2-rpc server), the default DirectURL can be read.
I have no idea why configuration.js does not work (zero knowledge in AngularJS).

Reproduction

On Linux

when accessing through file:/// then works well
using http://localhost/some/path/ then not working

okay, found the problem.
you should clean the cookies to make it working well.
in order to clean cookies, you MUST leave the index.html page first, since it will constantly set cookie/set cookie when leaving page.

easy way is to leave the page and remove all cookies
better way is to remove the cookies using developer tools.

@no1xsyzy You are correct. I should make sure the cookies of aria2-WebUI is completely clear first. Now configuaration.js works like a charm. Thank you for your help!

I cleared cookies in my browser but it doesn't work. I tried firefox and tried editing js/services/rpc/rpc.js and tried to change client. None of them works.
