Response. Flush () Usage

Response. Flush () is used to output the buffer information to the page.

For example, when you click a button to execute multiple tasks, each task has a response. Write ("Success message") after successful execution ").

If we add response. Flush () after response. Write ('success information'), the result is that after each task is executed, the information is directly output to the page.

If there is no response. Flush (), all response. Write ("information") will be output together after all tasks are completed.
