Web Page Modules

Each Web page module has a page producer associated with it. When a request is received, the page dispatcher analyzes the request and calls the appropriate page module to process the request and return the content of the page.

Like Web data modules, Web page modules are containers for components. A Web page module is more than a mere container, however. A Web page module is used specifically to produce a Web page.

Page producer component

Web page modules have a property that identifies the page producer component responsible for generating content for the page. The WebSnap page module wizard automatically adds a producer when creating a Web page module. You can change the page producer component later by dropping in a different producer from the WebSnap category . However, if the page module has a template file, be sure that the content of this file is compatible with the replacement producer component.

Page name

Web page modules have a page name that can be used to reference the page in an HTTP request or within the application's logic. A factory in the Web page module's unit specifies the page name for the Web page module.

Producer template

Most page producers use a template. HTML templates typically contain some static HTML mixed in with transparent tags or server-side scripting. When page producers create their content, they replace the transparent tags with appropriate values and execute the server-side script to produce the HTML that is displayed by a client browser. (The XSLPageProducer is an exception to this. It uses XSL templates, which contain XSL rather than HTML. The XSL templates do not support transparent tags or server-side script.)

Web page modules may have an associated template file that is managed as part of the unit. A managed template file appears in the Project Manager and has the same base file name and location as the unit service file. If the Web page module does not have an associated template file, the properties of the page producer component specify the template.
