There are three different caches involved in WebKit on Mac OS X.
A) The resource cache in the NSURL networking layer, which caches
both in memory and on disk.
B) The resource cache inside WebCore, which caches in memory.
C) The page cache in WebCore, a higher level cache which only
affects "go back" and "go forward" commands.

> cachedResponse forRequest methods
To turn off cache (A) you can call:
[[NSURLCache sharedURLCache] setMemoryCapacity:0];
[[NSURLCache sharedURLCache] setDiskCapacity:0];
> WebPreferences *prefs = [webView preferences];
> [prefs setUsesPageCache:NO];
The code above turns off cache (C).
One way to turn off cache (B) is to do this:
I suggest giving that a try.
