L = Tomcat Software based load balancersI believe it is a common practice to use Apache as the websever and also the Load balancer on your iselevel web application. however, sometimes it may be an overkill for a small scale project. e.g. in my previousproject, all we need is a easy-to-config, easy-to-use and https-enabled small daemon which cocould be runningon our not-so-good server (doubled as a MySQL NDB cluster management node ). I have tried quite a few, and following are which I made them work. and PoundIs my choice as it is the onlyone support HTTPS. BTW, the executable is only 140 K. Balance @ http://www.inlab.de/balance
