Hi,
I failed to mention that we are looking at apache/jserv
load-balancing/fail-over capabilities for HTTP/FTP and our client will post
data from a java program. No browser is involved. Cookies are useless in
this case ?? Data will flow from various clients, probably posted from java
program client agents.
bye,
Mohan

Subject: Re: HTTP fail-over
I don't know how exactly we can acheive this. I have done like this.
Write a program which establish a connection with your server. If it throws
any
exception then it means that it's down.
Please see the code listed here,
try {
URL url = new URL(server);
System.out.print("Server : " + url.getHost());
URLConnection urlCon = url.openConnection();
urlCon.connect();
System.out.println(" Alive");
}
catch(Exception e) {
System.out.println(" *** Down ***");
}
Hope this help you.
