httpclass becoming sticky?

Have a problem where httpclass is being sticky.

vip a snat pool a default pool a http profile a http class a

pool a single member 2.2.2.2:80

pool b single member 2.2.2.2:60

snat pool a - three addresses on inside network

http profile a - default settings

http class a - match host "my.site" match uri pattern "/apalm*" send to pool b no uri rewrite

1. Open site http://mysite/place/home.aspx - 200 OK

2. Click link takes us to http://mysite/apalm/ - 200 OK

3. Click link takes us back to http://mysite/place/home.aspx - 404 Not Found

Web logs show is that it is calling http://mysite/place/home.aspx on the wrong site in pool b

Fiddler shows Transport - Connection: Keep-Alive

Any ideas why this might be happening? How can I turn off keep alive to see if that is the problem?
