http://serverfault.com – what reverse proxy server will direct traffic to healthy servers whose health is based on a result string?? ideally i'd like something like dnsmadeeasy or ultradns - lol - but for reverse proxy i have looked at pound, delegate, ha proxy, squid, varnish, nginx, apache, and cherokee but can't see that they will work - they only test for HTTP result code scenario client request www.aaa.com www.aaa.com is a reverse proxy reverse proxy looks at "test.php" on server 1.aaa.com, 2.aaa.com and 3.aaa.com for result string "OK" if the server is "OK" then proxy requests to them help!
