I felt like I'm having the same issues as addressed here. But everything I try doesn't seem to work.
The program goes as follows:
- I'm asking for user credentials (username/password)
- Then I do some calls to the server downloading information.
- When its finished, I display a set of users, the user clicks on one, then is asked for the password for that account
- I then make another request to the server and check to see if I get the right information back (therefore verifying the username/password just given is correct)
The problem is, the last call is similar (same url, different credentials) to one that I do in the initial download. Regardless of what the user puts in for the second credentials the "correct" information comes back. I think this is because it is caching the response, but I can't figure out how to stop it from doing that.
I'm have a class that makes the connection and returns the downloaded data. And I make a new class for every connection. So I'm not really sure why its saving data.
I have a NSMutableURLRequest in which I do the following:
[theRequest setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
(I have also tried, NSURLRequestReloadRevalidatingCacheData and NSURLRequestReloadIgnoringLocalAndRemoteCacheData)
I've also implemnted the functions:
- (NSCachedURLResponse *)connection:(NSURLConnection *)connection
willCacheResponse:(NSCachedURLResponse *)cachedResponse {
return nil;
}
- (BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection {
return NO;
}
With the last one I don't fully understand it. So I tired YES and NO. And I've tried various NSURLRequest cache policies.
Any help on what my issue might be would be very helpful. Thank you.
