Rails will page cache all actions but one....why?

I have page caching turned on for all actions in my controller
(pragmatic is it’s name). Rails will cache each actions except for
one.
I’ll list the three ways this action can be called. It is only cached
one of the ways. Can somebody help?

http://www.recentrambles.com/pragmatic/index - This will not cache
httphttp://www.recentrambles.com/pragmatic This will not caches
http://www.recentrambles.com/ This will cache

All three point to the index action of my pragmatic controller. Here is
my relevant routes

map.connect ‘/pragmatic’, :controller => “pragmatic”
map.connect ‘’, :controller => “pragmatic”

I’m running off the rails trunk.
