The thing that strikes me is that asking for a particular key works as
expected.
Can I port the stored keys with
tie %A, "SDBM_File", "application", O_RDONLY, 0660;
tie %B, "DB_File", "new/application", O_CREAT|O_RDWR, 0660, $DB_HASH ;
%B = %A;
untie %A;
untie %B;
and restart apache ?
Also, GDBM_File looks a little faster than DB_File. Would I want to use
that instead ?
