5. Displaying a WEBDEV Session site
The following operations are performed when displaying a WEBDEV page in Session mode: - Page display request.
- The WEBDEV engine is started. This engine remains on the server until the application is closed.
- The application context is created. 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,
- contexts of data files, etc.
The page contexts remain in memory on the server until the end of the WEBDEV session. When the same page is called several times: - If PageDisplay is called to display the page, the page context is deleted and created again.
- If PageRefresh is called to display the page, the same page context is used again.
The WEBDEV session and the page contexts are automatically managed by default. No programming is required.
