NSMutableURLRequest timeout interval not taken into consideration for POST requests

Solution 1:

According to a post on the Apple developer forum, the minimum timeout interval for POST is 240 seconds. Any timeout interval shorter than that is ignored.

If you require a shorter timeout interval, use an async request along with a timer and call cancel on the NSURLConnection as needed.

Solution 2:

iOS 6 has fixed this issue.

NSMutableURLRequest *request = [NSMutableURLRequest 
                                requestWithURL:[NSURL URLWithString:url] 
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20];

[request setHTTPMethod:method];
[request setHTTPBody:requestBody];
NSLog(@"%f", [request timeoutInterval]); 
//20.0 in iOS 6
//240.0 in iOS 4.3, 5.0, 5.1

Solution 3:

Fixed with Clay Chambers's suggestion: with a custom timer Added a timer in a subclass of NSURLConnection

if (needsSeparateTimeout){

    SEL sel = @selector(customCancel);

    NSMethodSignature* sig = [self methodSignatureForSelector:sel];

    NSInvocation* invocation = [NSInvocation invocationWithMethodSignature:sig];

    [invocation setTarget:self];

    [invocation setSelector:sel];

    NSTimer *timer = [NSTimer timerWithTimeInterval:WS_REQUEST_TIMEOUT_INTERVAL invocation:invocation repeats:NO];

    [[NSRunLoop mainRunLoop] addTimer:timer forMode:NSDefaultRunLoopMode];

}

In the custom cancel method the connection is cancelled

[super cancel];
