Re: serving multiple shape files with Linklayer

Hi,

I am running multiple ShapeLinkServers to serve up multiple shape
files. I am not so clued in on sockets and servers, and I was
wondering what happens when lots of applets start hitting the same
servers. Right now I am lucky enough that only one person is using
my applet to process data, but that may change in the future.

I wrote another layer server for my own GPS/database data source
that works via a Java client implementation of XML-RPC---mostly to get
around the applet same-server requirement (the xmlrpc server is on the
same machine, but it routes calls for services to other machines (my
database server)). The other advantage is the client just has to know
one socket, one function name, but I can move the actual client elsehwere
If I need to.

I am a little more confident about multiple hits on the XML-RPC server,
and so I was wondering if it would be worth it to wrap the ShapeLinkServer
in xml-rpc server calls. Any thoughts?
