On that note; when running the Java web server was the only scalable way to
do java server-side, we used the proxy module to forward requests matching
certain characteristics (i.e. <Location *.jtml>) on to the Java server.
This worked pretty well, but the mod_jserv solution I'm sure will be
faster.  I bring this up because maybe there's a need for generalizing the
wire protocol between mod_jserv and the java VM, into something that could
be, for example, a perl engine running on the backend; that way a process
just serving images wouldn't be bogged by the memory perl takes up.
Thoughts?
