You could try to stick the _cache_serial to something shared between the servers, like this: Index: Smarty_Compiler.class.php =================================================================== RCS file: /repository/smarty/libs/Smarty_Compiler.class.php,v retrieving revision 1.371 diff -u -r1.371 Smarty_Compiler.class.php --- Smarty_Compiler.class.php 5 Aug 2005 20:53:04 -0000 1.371 +++ Smarty_Compiler.class.php 1 Sep 2005 09:38:16 -0000 @@ -2213,7 +2213,7 @@ $_cacheable = !isset($this->_plugins[$type][$name]) || $this->_plugins[$type][$name][4]; if ($_cacheable || 0<$this->_cacheable_state++) return ''; - if (!isset($this->_cache_serial)) $this->_cache_serial = md5(uniqid('Smarty')); + if (!isset($this->_cache_serial)) $this->_cache_serial = md5($this->_current_file); $_ret = 'if ($this->caching && !$this->_cache_including) { echo \'{nocache:' . $this->_cache_serial . '#' . $this->_nocache_count . '}\';}'; So that all servers compile the same templates with the same cache_serials. I'm not 100% sure if this has any negative side-effects, but i cannot think of any. greetings messju > /Nichlas
