Memcached vs regex fragment expiry


I thought i’d give memcached a try. Installed it all, made the change
in environment.rb and it all seems ok. I can telnet to memcached
process and manually retrieve the data being cached.

However, when I try to expire a fragment using a regex, eg:


it throws an error:

undefined method `delete_if' for #<MemCache:0x2289968>

I’m assuming i’m doing something stupid… Should the above work?
Have I missed out a vital step?

Oh well, back to the FileStore for now. :frowning:
