Memcached is an open-source project. There is nothing stopping you from making that change yourself and using it. However, you will have a hard time finding someone to do that feature for you for free, because quite frankly it is highly unlikely that anyone using memcached the way it was intended will have a use for it.
What you are requesting is actually the opposite of how memcached was designed. And is not really a trivial fix. 2009/3/24 gf <[email protected]> > > So?
