Thanks Jesse, :) For this project we are not using dojo (yet) but we
will for the upcoming projects. What did solve my problem was:
req.setRequestHeader( "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT" );
I know this is very fragile, but we are in a rush here, tomorrow, we
have a presentation with some big shots to present the application.
I found:
http://en.wikipedia.org/wiki/XMLHttpRequest#Microsoft_Internet_Explorer_cache_issues
which do explain a lot about it.
It's funny, back in 1997, when I was a ColdFusion developer, I always
need to worry with netscape 3.0, because IE 4.0 always parsed
everything (for good or bad). Today, its totally the opposite....

This is the annoying IE bug. Even with the best cache breaking strategies
setup you won't be able to fix it unless you make the urls being used
unique. With dojo all you have to do is set preventCache:true in the
dojo.io.bind calls.

Oracle AS is the worst application server in the world. Avoid it at
all cost. You always have alternatives:
Jboss, Websphere, BEA, Geronimo, Jonas, anything is better than that.
