- Overview
- Pages in session mode
- SEO-ready pages in Session mode
WEBDEV includes several types of pages to create dynamic sites: Pages in Session mode, as their name suggests, use sessions. This session is created on the server side when the first page of the website is displayed, and contains all the elements required to exchange data with the user. This session remains on the server until the user logs out, or until a given timeout is reached. The following operations are performed to display a page in Session mode: - Request page display.
- Start WEBDEV engine. This engine remains on the server until the application is closed.
- Create the application context. This context remains on the server until the application is closed.
- The WEBDEV engine executes the server code and builds the HTML page (e.g., from the data in the database).
- Once the HTML page is entirely built, the server transmits the result to the client (the browser).
A page context is automatically created on the server each time a page is displayed in the browser. This page context contains all the elements required to build the page viewed by the end user: - global variables,
- local variables,
- server processes,
- database connections,
- file contexts, etc.
The page contexts remain on the server until the end of the WEBDEV session. Pages in Session mode cannot be used for SEO purposes. The WEBDEV session and the page contexts are automatically managed by default. No programming is required. SEO-ready pages in Session mode SEO-ready pages in Session mode also use sessions. However, the session is not created when the first page of the website is displayed, but when any page of the website is displayed. Since all SEO-ready pages in Session mode can be used for SEO, they can be displayed independently, via a specific URL. If necessary, the session is automatically recreated when the user requests a page via this URL. The next pages displayed from this page will use the same session.
