[remm]

Author: remm
Date: Tue Dec 20 09:02:33 2005
New Revision: 358036

URL: http://svn.apache.org/viewcvs?rev=358036&view=rev
Log:
- Add two system properties (as given the JSP API, there is no easy solution to
  retrieve configuration parameters elsewhere) to allow configuring Jasper
  memory management. Note that changing from the defaults may affect
  performance, depending on the application.
