The "include flush" statement in JSP is used to flush the output buffer before including the specified page or file.
By default, JSP pages use a buffer to store the page content before sending it to the client. This buffering improves performance by reducing the number of times the server has to communicate with the client. However, sometimes it is necessary to flush the buffer before including a page or file.
The syntax for including a page or file with flush is as follows:
```
<%@ include file="filename" flush="true" %>
```
The flush attribute is set to "true" to indicate that the output buffer should be flushed before including the specified file. This ensures that any content that has been buffered up to that point is sent to the client before the included file is processed.
Using "include flush" can be useful in situations where you need to ensure that certain content is sent to the client immediately, rather than being held in the buffer. However, it can also impact performance, so it should be used judiciously.
