iOS Caching Problem

[Ploetzeneder]

Hello,
i have the following now:

	[[NSURLCache sharedURLCache] removeAllCachedResponses];
	[[NSURLCache sharedURLCache] setMemoryCapacity: 0];
	[[NSURLCache sharedURLCache] setDiskCapacity:0];
	NSURLCache *sharedCache = [NSURLCache sharedURLCache];
	[sharedCache removeAllCachedResponses];

	xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];
	[xmlParser setDelegate:self];
	[xmlParser parse];

and the Problem is, that somewhere it caches the content, the xmlURL is always the same, the content changes, i want to force the xmlParser to reload this?

Any ideas?
It is quite urgent , i am student and i need it untill this week, so paying 50 Euros to solve this would not be the problem.
The simulator works perfect but on the device there are problems.
