Sorry I didn't see your reply earlier due to digest mode...
I have confirmed with Wireshark that my test download file:
http://google-web-toolkit.googlecode.com/files/gwt-mac-1.5.2.tar.gz
includes and ETag.
Then I do this:
- (void)cancel
{
[download cancel];
resumeData = [download resumeData];
if (resumeData == nil)
{
NSLog(@"STILL No resume data :(");
}
[self setDownloading:NO];
}
And still the result is no resume data.
Any ideas or working examples?
