wow debugged to fix some real bad issues on this server …

  • the DR2.NET (my provider) CRON jobs run in my home while CGIs are executed in the directory they are in – that makes all sorts of relative path-configurations a horror and multiple root for defects on your site
  • MTAmazon (version 2.22) expires cached files after a hardcoded time to 3600 seconds (1 hour) which causes in a regular rebuild after a few hours a Cache-Miss for every fetch and therefore causing a big CPU and net load
  • MTAmazon (version 2.22) cannot handle “too long” filenames for it’s cached directories
  • when you specifiy the attribut DEBUG=“1” in your MTAmazon tag you get some useful output for finding bugs

result: much better speed in rebuilding, because – oh wonder – the cache suddenly worked !
