NAME

6       Webapp::storeFunction - Save application state persistently.
7

SYNOPSIS

9       String storeFunction( String(String) storer, b(a) fn, a state )
10

ARGUMENTS

12       storer  A  function  that  stores the state (which will be encoded as a
13       String) and returns a key that can be used to retrieve it.
14
15       fn The function to call when the state is retrieved.
16
17       state The state to pass to fn
18

DESCRIPTION

20       This lets you save application state  and  a  handler  function  to  an
21       external  source, and get a key to retrieve it later. The storage func‐
22       tion should throw an exception if it is unable to store the state. Oth‐
23       erwise  it  should  return a key that can be used with Webapp.retrieve‐
24       Function (3kaya) to execute the state later. This lets  you  make  URLs
25       much shorter than is possibly by passing the state directly.
26
27       You  may need to consider expiring old and unused states from your per‐
28       sistent storage if they have not been retrieved for some time.
