how to to Properly Handle HTTP Redirects with NSURLSession in Objective-C - Getting 302 Response but No Redirect
I keep running into This might be a silly question, but I'm working on an iOS app using Objective-C that makes network requests with NSURLSession. Recently, I encountered an scenario where my app does not follow HTTP redirects correctly. Specifically, when I make a request to a URL that returns a 302 status code, the response does not automatically redirect to the new location provided in the `Location` header. Instead, I get the response but no new data, and the completion handler simply receives the original response. Here’s a simplified version of my code: ```objective-c NSURL *url = [NSURL URLWithString:@"http://example.com/redirect"]; NSURLSession *session = [NSURLSession sharedSession]; NSURLSessionDataTask *dataTask = [session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *behavior) { if (behavior) { NSLog(@"behavior: %@", behavior); } else { NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response; NSLog(@"Response code: %ld", (long)httpResponse.statusCode); if (httpResponse.statusCode == 302) { NSLog(@"Redirect detected. Location: %@", httpResponse.allHeaderFields[@"Location"]); } else { // Process data } } }]; [dataTask resume]; ``` I’ve checked the app transport security settings in my `Info.plist`, and they allow HTTP connections. Additionally, I’ve confirmed that the response headers do have the correct `Location` field. I’ve also tried using `NSURLSessionConfiguration` to explicitly allow for redirects, but the behavior remains the same. Am I missing something fundamental about how NSURLSession handles redirects? Is there a way to manually follow the redirect if automatic handling is not working for some reason? For reference, this is a production REST API. Thanks, I really appreciate it!
