    copied!<p>i've been searching stackoverflow, google, apple and other places. The tips provided look promising, i implemented them but alltogether don't seem to work or get enforced. </p> <p>Problem: I have an <code>NSURLConnection</code> with specific credentials. I then have a logout where I clear the credentials, the protectionspace, i remove all cached responses and delete all cookies in the <code>sharedHTTPCookieStorage</code> but when calling my authenticated request again a few seconds later even with wrong credentials I still am using the old (deleted) credentials</p> <p>Here are some code extracts, where credentials are removed</p> <pre><code> NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials]; if ([credentialsDict count] &gt; 0) { // the credentialsDict has NSURLProtectionSpace objs as keys and dicts of userName =&gt; NSURLCredential NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator]; id urlProtectionSpace; // iterate over all NSURLProtectionSpaces while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) { NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator]; id userName; // iterate over all usernames for this protectionspace, which are the keys for the actual NSURLCredentials while (userName = [userNameEnumerator nextObject]) { NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userName]; WriteLog(@"Method: switchView removing credential %@",[cred user]); [[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace]; } } } </code></pre> <p>I then remove all cached responses</p> <pre><code> NSURLCache *sharedCache = [NSURLCache sharedURLCache]; [sharedCache removeAllCachedResponses]; </code></pre> <p>I then delete all cookies</p> <pre><code> NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; NSArray *cookies = [cookieStorage cookies]; for (NSHTTPCookie *cookie in cookies) { [cookieStorage deleteCookie:cookie]; NSLog(@"deleted cookie"); } </code></pre> <p>I also tried using no cookies and other policies</p> <pre><code> NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60.0]; [request setHTTPShouldHandleCookies:NO]; if(self.currentCookies != nil){ [request setAllHTTPHeaderFields: [NSHTTPCookie requestHeaderFieldsWithCookies:nil]]; } theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; </code></pre> <p>I also tried this hint here on specifically storing the cookies and passing them again. <a href="http://www.hanspinckaers.com/multiple-nsurlrequests-with-different-cookies" rel="nofollow noreferrer">http://www.hanspinckaers.com/multiple-nsurlrequests-with-different-cookies</a>. There's another blog on the web suggesting to add a "#" to each URL in order to enforce reauthentication, which works but just does not solve the issue because I need to count on session's credentials and the ability to use totally different credentials.</p> <p>Is this a bug or known issue and how do I really solve this... Put bluntly: What am I exactly doing wrong here?</p> <p>This is really bugging me and keeping me from continuing my work.</p> <p>I would greatly appreciate any input!</p> <p>Thanks alot!</p>
