'NSURLSession - download and do *not* decompress gzip?
I'm using NSURLSession's dataTaskWithRequest to download a file. It's gzipped, and it is automatically decompressed. However, I don't want it to be - I want the gzipped source. Is there any way to disable decompression?

NSURLSession automatically inserts this value to your request's header:
"Accept-Encoding: gzip;q=1.0, compress;q=0.5"
which causes the downloaded data to be automatically decoded. So I think you should start by replacing the value of "Accept-Encoding" with something else.

maybe this will reslove:
- (BOOL)download:(NSURLDownload *)download shouldDecodeSourceDataOfMIMEType:(NSString *)encodingType;

It all depends on the Content-Type, if the Content-Type says it's text/html, it doesn't matter whether it's zipped or not, Task will call completion with text/html bytes.
Anyhow, if you have the wrong Content-Type, and still want this, you can instance NSURLDownload (it's the legacy url loading system), implement and set a delegate (NSURLDownloadDelegate), and in your delegate implement this:
- (BOOL)download:(NSURLDownload *)download
shouldDecodeSourceDataOfMIMEType:(NSString *)encodingType {
return NO;
}
There's no way to do it with URLSession AFAIK, except of course implementing your own protocol, but that might be too much.
