Proxy Throughput Round-Robin
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.
