The key to getting around this issue is to upload the file using a stream. When using NSMutableURLRequest, this can be accomplished using something similar to the following:

NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPBodyStream:[NSInputStream inputStreamWithFileAtPath:filePath]];

When using ASIHTTPRequest, streaming a file is accomplished with this:

ASIHTTPRequest* request = [ASIHTTPRequest requestWithURL:url];
[request setPostBodyFilePath:filePath];
rRequest.shouldStreamPostDataFromDisk = YES;
