Tomcat supplies methods such as getBufferSize and setBufferSize for buffering responses back incrementally to the browser. In a typical Tomcat implementation using these buffering methods, the page the user sees in the web browser is built in stages. For example, the web application logic might buffer the text back, and then shortly afterward the web application logic would buffer back the remaining graphics.

In the webMethods Tomcat implementation, web page content cannot be buffered back to the browser incrementally because Integration Server does not support incremental buffering of HTTP responses. Your web applications can still include the Tomcat buffering methods, but they will not function in the typical way. When a web application uses these buffering methods, the WmTomcat logic will accept the incremental buffers and hold incremental content in memory. After the entire web page response is complete, the WmTomcat logic will buffer the full page to the browser at one time.
