NAME
       Webapp::storeFunction - Save application state persistently.


SYNOPSIS
       String storeFunction( String(String) storer, b(a) fn, a state )


ARGUMENTS
       storer A function that stores the state (which will be encoded as a String) and returns a key that can be
       used to retrieve it.

       fn The function to call when the state is retrieved.

       state The state to pass to fn


DESCRIPTION
       This lets you save application state and a handler function to an external  source,  and  get  a  key  to
       retrieve  it  later.  The  storage function should throw an exception if it is unable to store the state.
       Otherwise it should return a key that can be used with Webapp.retrieveFunction  (3kaya)  to  execute  the
       state later. This lets you make URLs much shorter than is possibly by passing the state directly.

       You  may  need  to  consider expiring old and unused states from your persistent storage if they have not
       been retrieved for some time.
