I don't have Jason Hunter's Servlets book, so I'd appreciate it if you could
describe how this could be done.

In order to mitigate the all-or-nothing issue, I am hopeful that the web
server could be configured to only route JSPs in a specific path to go
through my "JSP wrapper" servlet. For instance, "http://host/foo/a.jsp"
would go through my JSP wrapper servlet, whereas "http://host/bar/a.jsp"
would not. This is do-able with JRun for servlet processing, so maybe we
could do the same for JSP processing.
