Change baseUrl on the fly ember-cli

Question

I want to do some ember routing from another domain: Example:

m.site.com/foo
site.com/path/to/ember/bar

So, I have to change the root path "on the fly", depending on which domain the script is executed

I'm trying to add rootURLinEmber.Router

var Router = Ember.Router.extend({
  location: 'hash'
    rootURL: '/path/to/ember/'
});

and change app-config-from-meta.js in ember-cli

    try {
      var metaName = prefix + '/config/environment';
      var rawConfig = Ember['default'].$('meta[name="' + metaName + '"]').attr('content');
      var config = JSON.parse(unescape(rawConfig));

   if (window.location.href.indexOf('m.') !== -1) {
            config.baseURL = '/path/to/ember/';
            config.locationType = 'hash';
      }
    console.log(config);
      return { 'default': config };
    }
    catch(err) {
      throw new Error('Could not read config from meta tag with name "' + metaName + '".');
    } 

but it doesn’t help.

Update:

The problem was in the tag '<base href="' + baseURL + '">'that was inserted during the build. Therefore, since I understand that I need to create an alternative index file, for example, index.htmland index_bar.html. What is easier to do with it?

Update: My awareness: Added to broccoli-config-replaceaction process.

if (filePath.indexOf('index_bar.html') > 0){
        var tmpConfig = config;
        tmpConfig.baseURL = config._chatBaseURL;
        tmpConfig.locationType = config._chatLocationType;
        this.processFile(tmpConfig, filePath, destPath);
    } else {
        this.processFile(config, filePath, destPath);
    }

index.htmlworks with autorouting and base/

index_bar.htmlworks with hashrouting and base/path/to/ember/

Any better solution? Thanks
