title: NSURLErrorDomain error -1012
body: <p>I need to parse a xml file from a password protected URL I tried the following</p>
  
  <pre><code>NSURLCredential *credential = [NSURLCredential credentialWithUser:@"admin"  password:@"123456" persistence:NSURLCredentialPersistenceForSession];
  NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
                                           initWithHost:@"xyz.com"
                                           port:80
                                           protocol:@"http"
                                           realm:nil
                                           authenticationMethod:NSURLAuthenticationMethodDefault];  
  [[NSURLCredentialStorage sharedCredentialStorage] setCredential:credential
                                               forProtectionSpace:protectionSpace];    
  url = [NSURL URLWithString:urlString];
  NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
  [request setHTTPMethod:@"GET"];
  [request setValue:@"application/xml" forHTTPHeaderField:@"Content-Type"];
  connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
  NSURLResponse *response;
  NSError *error;
  NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse: &amp;response error: &amp;error];   
   NSString *dataStr=[[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding]; 
   NSLog(@"data == %@\n error in connecting == %@",dataStr,error);
  </code></pre>
  
  <p>I got the following response</p>
  
  <pre><code>data == &lt;!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"&gt;
  &lt;html&gt;&lt;head&gt;
  &lt;title&gt;401 Authorization Required&lt;/title&gt;
  &lt;/head&gt;&lt;body&gt;
  &lt;h1&gt;Authorization Required&lt;/h1&gt;
  &lt;p&gt;This server could not verify that you
  are authorized to access the document
  requested.  Either you supplied the wrong
  credentials (e.g., bad password), or your
  browser doesn't understand how to supply
  the credentials required.&lt;/p&gt;
  &lt;p&gt;Additionally, a 401 Authorization Required
  error was encountered while trying to use an ErrorDocument to handle the request.&lt;/p&gt;
  &lt;/body&gt;&lt;/html&gt;
  </code></pre>
