As already indicated, using the CGI parameter as a task identifier is an example of a necessity practice. Regardless of the client calling the server and using the same task identifier, the same results would be generated. The problem with using a task identifier of 20 is that the task identifier has to be determined by the server, and not the client, adding a wrinkle to the solution. The implementation of the pattern is a server push, without user authentication. Looking back at the Persistent Communications pattern implementation, the server push used authentication, and that would seem to be a conflict in this implementation. The Infinite Data pattern uses a shopping cart approach, where the identification of the user will use an HTTP cookie. Using cookies or authentication is not a necessity, but a nice-to-have feature. Otherwise, anybody can access a specific task. For example, if the URL is /ajax/chap08/PrimeNumberHandler. ashx task=1234, not using an HTTP cookie as an authorization mechanism would allow everybody to retrieve the results for task 1234.

For the scope of the prime number application, the HTML client is used to define and process the prime number. The HTML client presents an HTML form consisting of a text box and button. The text box is used to define the maximum number for which all prime numbers are calculated. The button is used to submit the maximum number to the server. The results area displays the generated numbers. Figure 10-2 is the HTML page used to process two prime numbers.

Figure 10-2 shows two text boxes; one text box has the value of 200, and the other has the value of 1000. Each text box represents the maximum number to find all primes. The result area is where the text No Result is displayed. The Send Data buttons are used to send the maximum number value to the server. The Start Communications and End Communications buttons are used to start and stop the Persistent Communications pattern. These two buttons are not necessary and can be automatically controlled by the Send Data buttons. They were kept in the HTML page to illustrate how the Persistent Communications and Infinite Data patterns work seamlessly together.

The implementation of the HTML page will be presented as a series of code segments. The first code segment is the overall HTML page, with most of the implementation missing for clarity purposes. Then as needed each missing code segment will be illustrated and explained. The overall structure of the HTML page illustrated in Figure 10-2 is as follows: <html> <head> <title>Infinite Data</title> <script language="JavaScript" <script language="JavaScript" <script language="JavaScript" <script language="JavaScript" E B V N <script language="JavaScript"

CHAPTER 10 INFINITE DATA PATTERN
<tr> <td colspan="4"><span id="result2">No Result</span></td> </tr> </table> </body> </html> The HTML page implementation, like previous pattern implementations, includes a number of JavaScript files referenced by using the script HTML tag. Unlike previous patterns, on the client side the Infinite Data pattern does not reference any script files that implement a generic Infinite Data infrastructure. There is no Infinite Data infrastructure; the activity diagram illustrated in Figure 10-1 shows that all of the logic is application specific. The Infinite Data pattern does instantiate the ClientCommunicator type that is an implementation of the Persistent Communications pattern. The instantiated Persistent Communications pattern is assigned to the variable client, and the property baseURL is assigned to the file /ajax/ chap08/PrimeNumberHandler.aspx. The file /ajax/chap08/PrimeNumberHandler.aspx represents the server-side implementation of the Infinite Data pattern. The HTML page contains the HTML element table that contains four rows used to send and receive the Infinite Data state. When the buttons that have the onclick event handlers defined as SendData1 or SendData2 are clicked, the structure is assembled and sent for processing to the server. The sent structure is stored in the input elements with the identifiers number1 and number2. When the result structures are received, they are processed and inserted into the span elements with the identifiers result1 and result2.
