Why isn't getSession() returning the same session in subsequent requests distanced in short time periods?

Question

I am sending a $.getJSON (HTTP GET) request twice (with different data), one after another (lets say we have request1 and request2). I can see in the developer tool

Just store your cookie(with JESSIONID) in Client , when your send subsequent request to Server , put the stored cookie in your request header field and send, then you will get the same session in the server end.

CLIENT(IOS) store your cookie from response:

    NSHTTPURLResponse* httpURLReqponse = (NSHTTPURLResponse*) response;
    NSDictionary* allHeaders = [httpURLReqponse allHeaderFields];
    NSLog(@"Response Headers : %@ ", allHeaders);
    NSString* cookie = [allHeaders objectForKey: @"Set-Cookie"];
    DATA.cookies = cookie;      // Store the cookie

CLIENT(IOS) send your subsequent request with cookie:

// Put the stored cookie in your request header
[(NSMutableURLRequest*)request addValue: DATA.cookies forHTTPHeaderField:@"cookie"];
[NSURLConnection sendAsynchronousRequest: request queue:[NSOperationQueue mainQueue] completionHandler:nil];

Not only for IOS client . Then , in the server end , you will get the same session:

Server(JavaEE) GET HttpSession:

// Get the session, print its hashCode. You will find out that it's same as previous.
HttpSession session = ServletActionContext.getRequest().getSession();
