Hi,
Here's a tidbit from the FAQ on Java Security (located at
http://java.sun.com/sfaq/#read)
1.What are applets prevented from doing?
In general, applets loaded over the net are prevented from reading and
writing files
on the client file system, and from making network connections except to
the originating host.
2.Can applets read or write files?
In Netscape Navigator 2.0, applets cannot read or write files at all.
Does this mean that in a client-server architecture (in which the client is
an applet
running within the Netscape 2.0 browser) the server must either
1) Reside on the 'originating host'?
or
2) Reside on a host other than the 'originating host' but reached via a proxy
service which resides on the 'originating host'? In this case the proxy
server
would simply act as a stream redirector.
Thanks for any help,
