It seems the MovableType Plugin that takes care of the enclosure portion of the RSS feed is causing the folks over at Libsyn some headaches. What has been happening apparently is that every time the RSS feed gets re-built the plugin reaches out and does a head request on the file. In my case my Podcast feed has the last 15 entries which will cause the plugin to do 15 head request of the file.
I am sure the folks at Libsyn are going to be talking to Brandon, but don’t you think it is about time that Six Apart implement enclosures as a core portion of the blog application. There has to be a better way to parse that info instead of doing it every single time.
This is causing a lot of unnecessary traffic as well, not to mention the undue loading on the servers at Libsyn.
