Hi,
I did what you said. I used NSURLConnection and at the end of the download I
save the NSData to the disk. Fine.
But, I cannot yet start a download from a given offset.
I did:
--------------------
NSURL *movieUrl = [NSURL URLWithString:movieLink];
NSURLRequest *theRequest=[NSURLRequest requestWithURL:movieUrl
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30.0];
And I tried to get the header fields with
--------------------
NSDictionary *dict = [theRequest allHTTPHeaderFields];
bul dict is always nil. Should I create it by myself?
How do create a new header field and set the offset?
Which name of the field does specify the offset value?
How to do? I am stoped here.
Thank you
Best Regards

You'd have to move to using NSURLConnection rather than NSURLDownload

Or, file a bug and ask that NSURLDownload support it natively. :-)
