  1. /*
  2. * if google autosuggest or autocomplete is on, then the following code does not work properly when proxyMode is partiallyOn
  3. * Eg: if user types aol it immediately hits google server for autosuggest and mustEnableProxy function below returns true since,
  4. * google is in proxyEnabledSites list. This connects thru proxy for aol.com which is wrong.
  5. * Autosuggest is disabled in epic so no prob currently.
