Some posts before and after
this, talk about a "service". It's not just something you just download, or as easy as the old configcache.xml... Also take a look at the link you have to put in:

If it was that simple, I think there would a patch already since '6.1.0000' that redirected the whole service to a local file being read... (would be indeed great though)
