[hunchentoot-devel] ht-simple-ajax

[Haris]

I removed some of the code but it doesn't work anymore.
What's the minimum code I have to add to make it works ?
I don't really get response and callback terms in ajax ?
I'm only interested in ajax now to be able to work with session values with 
javascript.
Now when I click on Say hi link, I only get messagge box with value 
"undefined".
