Show cached pages with boost for logged in users I have a website that is only available to logged in users, I want to increase performance with boost by caching pages for authenticated users would i just edit the code above?

http://drupal.org/node/509694

here it says this code is what prevents boost from caching for logged in users

&lt;?php
  // For authenticated users, set a special cookie to prevent them
  // inadvertently getting served pages from the static page cache.
  if (!empty($user-&gt;uid)) {
    boost_set_cookie($user);
  }
No, because it will break your site for logged in users. Try Authcache module instead.
