Functions of the flush attribute of JSP: Include

JSPMediumIncludeAnother file has a very biased attribute calledFlush, Default value:
False.

In the same
JSPIfIncludeItself (source file) will form an endless loop logically. By default, the server will wait until the file is read to the bottom and then output to the client, and destroy the request and response of the access. HoweverFlushWhen a property is assigned a true value, when a certain amount of data is accumulated in the cache, the server will first provide some data to the browser and wait for the subsequent content.
It can be concluded that this attribute is not taken into account on a simple page. When a page contains a large amount of data, some content can be output first to shorten the client latency. This attribute also has a corresponding application in servlet.
