Disable Ajax caching, just in case

Quoth Mike, on the NewsGroup:

I was experiencing some oddness (dead button clicks), but I'm not 100%
sure if caching was involved in the problem, for type "text" ajax
defaults to caching all responses - so I made the addition of

           cache: false,

on lines 177 and 213 to disable caching of the response coming back
from the server. The problem I was having "dead clicks" seemed to
have resolved.

Is it possible that the state and everything would be the same and not
cause a message to be sent due to caching? Either way, I'd rather
explicitly control caching than rely on a default.
