Understanding asp.net 2.0 asynchronous page processing process

Bkjia.com Network ProgrammingTo understand how to process asp.net 2.0 asynchronous pages, first list the page lifecycle:

1: init event: Page initialization and initialization settings.

2: loadviewstate method: load the view State and fill in the viewstate attribute.

3: loadpostdata method: process the returned data and input form data.

4: load event: load the page. The page control is initialized and reflects the client data.

5: raisepostdatachangedevent Method: A change event is triggered when a change notification is sent back.

6: raisepostbackevent method: process the send-back event, process the client events that cause the send-back, and raise the corresponding time on the service.

7: prerender event: Page pre-rendering.

8: saveviewstate method: Save the view State and save the viewstate attribute to the string.

9: render method: displays the page.

10: dispose method: determines whether to reference expensive resources.

11: unload event: uninstall page.

Page processing method:

1: synchronous processing;

2: asynchronous processing.

Synchronous request process:

1: When asp.net receives a page request, it extracts a thread from the thread pool and assigns the request to the thread.

2: The page retains the thread during this request to prevent this thread from being used to process other requests.

3: If a synchronization request requires a long operation time, the thread allocated to the request is suspended before the return result is called.

4: Wait for the thread to return and complete other lifecycle of the page.

The relationship between the synchronization request lifecycle and the thread:

• Four pages in total:
• Previous Page
• 1
• 2
• 3
• 4
• Next Page
