Hi Rainer, your comment about the watchdog sounds interesting. When you load balance it would seem useful to get feedback from Tomcat itself about its load so that the module can adjust dynamically its load (lbfactor) based on the Tomcat's performance rather than a session/socket count. One can wonder if such added complexity would be detrimental to the mod_jk stability.
