Re: cache problem with oscache

[Clinton Begin]

The OSCacheController is very simple.  You may want to check it out and verify that it uses OSCache properly for the latest version.  We really only support the tested version (i.e. not the latest). This is on our TO-DO list, but you can help by figuring this out.  :-)

Cheers,
Clinton
