Also, this page
(
https://glassfish.dev.java.net/javaee5/build/GlassFish_LB_Cluster.html)
needs some TLC. Some that I remember at the top of my head :
1. sun webserver 7.0 is out. this page mentions that GF is certified
with only 6.1
2. aslb plugin not available for 64-bit
3. the 10 odd steps to configure the lb plugin can easily be scripted
4. some typos in configuration steps
5. links to docs and explanation of tags noted in the emails below
Thanks
