[Mapserver-users] java connector

Hi,

I put my perl scripts inside the "cgi-bin" Apache HTTP server directory
and I invoke them through a HTTP connection. It may be not so fast as
invoke them directly but it's more flexible that way - and HTTP is a
very light protocol.

I'm not clear about the gain of performance but for now I prefer to not
touch the original mapserv.c.

I don't know if I understood well what you asked, but my perl scripts
work also with query string parameters as the mapserv do, and they can
give me an extent text to be parsed or just images...

I think the same about using JNI, but right now I don't have time for
that adventure :-) It would be interesting indeed and a big improvement
for mapserver.
