Hi ,
    In the Proxy Throughpult Round-Robin method for load balancing feature available in Apache web server,  The mapping rules are like this.
 
RewriteEngine on
RewriteMap    lb      prg:/path/to/lb.pl
RewriteRule   ^/(.+)$ ${lb:$1}           [P,L]
 
Where lb.pl is some thing like this.
 
#!/path/to/perl
##
##  lb.pl -- load balancing script
##

$| = 1;

$name   = "www";     # the hostname base
$first  = 1;         # the first server (not 0 here, because 0 is myself)
$last   = 5;         # the last server in the round-robin
$domain = "foo.dom"; # the domainname

$cnt = 0;
while (<STDIN>) {
    $cnt = (($cnt+1) % ($last+1-$first));
    $server = sprintf("%s%d.%s", $name, $cnt+$first, $domain);
    print "http://$server/$_";
}

##EOF##
 
It appends the path passed to it and constructs a new URL.
 
Is there any way In which I can send the cookie information to this perl script  as STDIN ?
 
Regards,
Adi.
