-// Implementation of ProxyConfigService that retrieves the system proxy
-// settings.
-//
-// It works by calling WinHttpGetIEProxyConfigForCurrentUser() to fetch the
-// Internet Explorer proxy settings.
-//
-// We use two different strategies to notice when the configuration has
-// changed:
-//
-// (1) Watch the internet explorer settings registry keys for changes. When
-//     one of the registry keys pertaining to proxy settings has changed, we
-//     call WinHttpGetIEProxyConfigForCurrentUser() again to read the
-//     configuration's new value.
-//
-// (2) Do regular polling every 10 seconds during network activity to see if
-//     WinHttpGetIEProxyConfigForCurrentUser() returns something different.
-//
-// Ideally strategy (1) should be sufficient to pick up all of the changes.
-// However we still do the regular polling as a precaution in case the
-// implementation details of  WinHttpGetIEProxyConfigForCurrentUser() ever
-// change, or in case we got it wrong (and are not checking all possible
-// registry dependencies).
