        2. Hi Mate,

          Smokin hot stuff! You’ve trimmed my dim. I feel as bright and fresh as your prolific website and blogs!

          I need to
          write some implementation of key delimiter value
          , the delimiter which received as parameter will used to write it to the DB as "keyDelimeterValue".

          after that, I need to retrieve the key and the value , the issue that this delimiter is defined by some custom code and could be any thing.
