I played around with it a little more and noticed that if I close the
browser and reopen the sites, I get different ones working. It appears
that Tomcat is setting a cookie to "stick" me to a particular worker.
So it appears that this is not the ideal way to have one server, many
sites, each with many host names.

I have for host pointing to each IP. This is my hosts file
172.16.10.39 site-1.com Works
172.16.10.39 www.site-1.com Gives me site2's content
172.16.10.39 other.site-1.com Works
172.16.10.39 site1.com Works
172.16.10.39 www.site1.com Works
172.16.10.39 other.site1.com Works
172.16.10.38 site-2.com Works
172.16.10.38 www.site-2.com Gives me site1's content
172.16.10.38 other.site-2.com Works
172.16.10.38 site2.com Works
172.16.10.38 www.site2.com Works
172.16.10.38 other.site2.com Works
This is very weird.
Any ideas?

the docs for jk2 suggest :
"tomcatId" is "Automatically set to the localname ( host:port )" and
that it "Must match the JVM route on tomcat the server.xml Engine
element, for load balancing"
So maybe:
[channel.socket:172.16.10.39:8009]
info=Ajp13 worker, connects to tomcat instance using AJP 1.3 protocol
tomcatId=site1
[channel.socket:172.16.10.38:8009]
info=Ajp13 worker, connects to tomcat instance using AJP 1.3 protocol
tomcatId=site2
and in server.xml:
<Engine defaultHost="Site1.com" name="Site1" jvmRoute="site1">
... etc ...
<Engine defaultHost="Site2.com" name="Site2" jvmRoute="site2">
