10 . The method of claim 9 , wherein the step of building a message in response to user selection of data content within the first portable document file comprises:

locating a data value corresponding to a document ID tag within hidden class data content of the first portable document file;

associating, and including in the message, the data value with the document ID tag in the message; and

locating, and including in the message, a data value and ID tag associated within hidden class data content that links to the selected data content.

11 . A client system for obtaining data content related to user selected data content within a portable document file, the client system comprising:

a) browser system for receiving an HTTP package containing a first portable document file, the first portable document file comprising display class data content selectable by the user and related hidden class data content;

b) a display module for displaying the display class data content on a display screen associated with the client system;

c) a message module for:

building a message in response to user selection of data content within the first portable document file, the message comprising both:

identification of the first portable document file; and

hidden class data content related to user selected display class data content;

sending the message to a message server; and

receiving a second HTTP package containing a second portable document file from the message server in response to sending the message.

12 . The client system of claim 11 , wherein the message module further provides for:

locating a data value corresponding to a document ID tag within hidden class data content of the first portable document file;

associating the data value with the document ID tag and including the data value and the associated document ID tag in the message; and

locating, and including in the message, a data value and ID tag associated within hidden class data content that links to the selected data content.

13 . The client system of claim 11 , wherein the message further comprises identification of the user of the client system.

14 . The client system of claim 13 , wherein message module further provides for:

obtaining a user ID from an operating system of the client system; and

associating the user ID with a user ID data tag in the message.

15 . The client system of claim 14 , wherein the message module further provides for:

locating a data value corresponding to a document ID tag within hidden class data content of the first portable document file;

associating the data value with the document ID tag and including the data value and the associated document ID tag in the message; and

locating, and including in the message, a data value and ID tag associated within hidden class data content that links to the selected data content.

16 . The client system of claim 11 , wherein the message module further receives a message server address as a message server address update message that is a file distinct from the first portable document file, the message server address being an address to which the message is sent.

17 . The client system of claim 16 , wherein the message module further provides for:

locating a data value corresponding to a document ID tag within hidden class data content of the first portable document file;

associating the data value with the document ID tag and including the data value and the associated document ID tag in the message; and

locating, and including in the message, a data value and ID tag associated within hidden class data content that links to the selected data content.

18 . The client system of claim 16 , wherein the message further comprises identification of the user of the client system.

19 . The client system of claim 18 , wherein message module further provides for:

obtaining a user ID from an operating system of the client system; and

associating the user ID with a user ID data tag in the message.
