Hi all, Am a beginner in objective C, i am implementing a function that would query a web server and display the returning string in console. I am calling the function (getDatafromServer) repeatedly in a loop. The problem is that the first time am getting the value whereas the other times, it returns me a (null) in console... I've searched about memory management and check out on the forums but none have worked. Can you please guys tell me where am wrong in the codes below? Thanks in advance....

@implementation RequestThread

+(void)startthread:(id)param{

 while (true) {
  //NSLog(@"Test threads");
  sleep(5);
  NSLog(@"%@",[self getDatafromServer]);
 }

}

+(NSString *) getDatafromServer{

 NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

 NSString *myRequestString = @"name=Hello%20&[email protected]";

 NSData *myRequestData = [NSData dataWithBytes:[myRequestString UTF8String] length:[myRequestString length]];

 NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString:@"http://192.168.1.32/gs/includes/widget/getcalls.php?user=asdasd&passw=asdasdasd"]];
 [request setHTTPMethod:@"POST"];
 [request setHTTPBody: myRequestData];
 [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
 NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

 NSString *myString = [NSString stringWithUTF8String:[returnData bytes]];

 [myRequestString release];
 [request release];
 [returnData release];

 return myString;
 [pool release];
}

@end
