1. A method of reducing the size of a message generated by a first computer for a second computer, comprising:

  • comparing the message at the first computer to one or more messages previously transmitted to the second computer;

    generating a delta message to describe a difference between said message and one of said previous messages;

    examining, in one of said message and said delta message, a value and a first data type associated with said value;

    replacing said first data type with a second data type requiring less storage space for said value;

    comparing a character string in one of said message and said delta message with a set of character strings stored in a first memory of the first computer; and

    replacing said character string with an identifier of said character string if said character string matches one of said character strings in said set of character strings.
