Question

I am using NSURLConnection to connect with a server, using a GET request. To login I am sending a GET request with url of the form

http://<myUserName>:<myPassword>@my.serverurl.com/user/login

an example URL will be

http://someusername:[e-mail]/user/login 

When I login for the first time, and I pass the correct username and password, I am able to successfully login, and if I pass incorrect username or password I get a response from server saying my username and password is incorrect.. All is well then

But when I login with correct username/password, get into my home page. There I logout to go back to login screen. Now I enter incorrect username and password and try to login, I am getting response login is successfull..This is my problem.

That means all my subsequent login requests return successfull with incorrect username and password. I checked the same url (correct and incorrect) with the browser and there everything is working as it should be.

This is the code I am using to login

-(void)postRequest{
    NSMutableURLRequest *request    =   [[NSMutableURLRequest alloc] init] ; 
    [request setURL:[NSURL URLWithString:
              @"http://myusername:[e-mail]/user/login"]]; 
    [request setHTTPMethod:@"GET"];
//    [request setHTTPShouldHandleCookies:NO];   ==> I tried without this first

    loginRequestConnection  =   [[CustomURLConnection alloc]
                                      initCustomURLWithRequest:request 
                                      delegate:self 
                                      withTAG:LOGIN_REQUEST_CONNECTION];
    [request release];
}

Now CustomURLConnection is nothing but a subclass of NSURLConnection and added a tag to identify between multiple connection requests in the delegate

@interface CustomURLConnection : NSURLConnection{
}
@property()NSInteger tag;
@property(nonatomic, retain) NSMutableData *receivedData;

-(id)initCustomURLWithRequest:(NSURLRequest *)request delegate:(id)delegate withTAG:(NSInteger)tagInt;
@end

I think the problem is NSURLConnection request is storing the cookie somewhere and reusing them to subsequent requests. That is why I added

[request setHTTPShouldHandleCookies:NO];

to the code. But with or without that problem persist. So any other suggestion to what is causing this problem?

Answer 1

try using this
initWithURL:cachePolicy:timeoutInterval: and set cache policy to NSURLRequestReloadIgnoringCacheData

Try adding this delegate method.

 - (NSCachedURLResponse *)connection:(NSURLConnection *)connection willCacheResponse:(NSCachedURLResponse *)cachedResponse {   
return nil; 
}

Ensure that this method is called.

Use NSURLCredentialStorage and removeCredential to erase your cache for credentials that are stored by NSURLConnection.

Please check this answer as well.

Hope that works
