Sample 26181: Generating a Please Wait Message
Users of Web applications expect results of their requests to be returned in a matter of seconds. For this reason, a Web-based application often uses a two-step approach to providing responses to users of a long-running process:
- First, provide an immediate response that says "Please Wait."
- Then replace the "Please Wait" message with the output from the process once it has been completed.
Such functionality is straightforward to implement using the Application Dispatcher.
This example deals with how output replaces “Please Wait” message.
An HTML template (as discussed in Section 7.5) is used to display the “Please Wait” message so the message can be used easily by multiple programs. Using HTML templates eliminates complicated quoting issues and makes it easy to generate and update HTML with an HTML editor. The HTML must be saved in a location known by the Application Server.
