/* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 * This fetches the header only for a remote page.
 * 
 * Pro's:
 * - when fetching static stuff (images, css, html)
 *   you can first compare modified date or statuscode (304) 
 *
 * Con's:
 * - hitting a heavy webapp with dynamic content might be slow,
 *   you essentially hit the remote page two times

{preload_replace:preload_trick="preload_replace"}
{embed="group/template" preload='{{preload_trick}:pre_url_title="special"}'}

embedded template

if called via embed you can override the preload_replace once more.
It will insert the embed-variable and parse it early.

/*

 - codeigniter, by default, uses persistent database connections, this is problematic in that the 
lock is never automatically released on connection termination (what else is to expect with persistent 
connections). However after a script ends you also never can RELEASE_LOCK() anymore, at least it didn't 
work overhere while testing. The script really has to make sure to release the lock before ending 
(shutdown_function) if it uses persistent DB connections.
