Create and load an NSURLConnection. If you're not connected to the

Just tried it.... [describes something different]
No, Garriet, you did not try what I said. Here is some code to get
you
started:
NSURL* url = [NSURL urlWithString:@"http://www.apple.com";] ;
NSURLRequest* request=[NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:65536.0];
// since timeoutInterval is broken, I set it to a large value and
// use an "external" NSTimer to time out.
NSURLConnection* connection = [NSURLConnection
connectionWithRequest:mutableRequest delegate:self] ;
Well, here is the code I used:
- (void)testUrll;
{
NSURL *theURL = [ NSURL URLWithString: @"http://www.mdenkmann.de"; ];
NSURLRequest *request = [ NSURLRequest requestWithURL: theURL
cachePolicy:
NSURLRequestReloadIgnoringCacheData
timeoutInterval: 65536.0
];
BOOL can = [ NSURLConnection canHandleRequest: request ];
NSLog(@"%s can %d",__FUNCTION__, can); // YES
NSURLConnection *cu = [ NSURLConnection connectionWithRequest:
request delegate: self ];
NSLog(@"%s cu %@",__FUNCTION__, cu);
}
- (void)connection:(NSURLConnection *)connection didFailWithError:
(NSError *)error
{
NSLog(@"%s %@ %@",__FUNCTION__, connection, error);
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:
(NSURLResponse *)response
{
NSLog(@"%s %@ %@",__FUNCTION__, connection, response);
}
And here is the result:
Near Phone (and modem not connected):

Immediate response. Ok.

You might observe a delay of 2 minutes.
Kind regards,
Gerriet.
