Asynchronous request dispatching settings

Use this page to enable the asynchronous request dispatcher (ARD), which enables servlets and JSP pages to make standard include calls concurrently on separate threads.

To view this administrative console page, click Servers > Server Types > WebSphere application servers > server_name > Web Container Settings > Web container > Asynchronous request dispatching.

Additionally, the initiation and the insertion of the include contents can be separated so that the include has more time to execute before it needs to be written to the response. ARD requires aggregation of the include contents with the original response. The application server can aggregate the contents in memory or the client browser can aggregate the contents through AJAX. Aggregation type is configurable at the application level.
