Problem with NSMutableURLRequest

Programming for iPhone: Problem with NSMutableURLRequest on newest questions tagged iphone – Stack Overflow

i have the following method

-(void)request
{
    responseData = [[NSMutableData data] retain];
    NSString *post =  [NSString stringWithFormat:@"id=%d&a_id=&d",1,1];
    NSLog(@"%@",post);
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

    request = [[NSMutableURLRequest alloc] init];

    [request setURL:[NSURL URLWithString:kWebURL@"/req/request.php"]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

    [request setHTTPBody:postData];
    [[NSURLConnection alloc] initWithRequest:request delegate:self];

    [postLength release];
    [postData release];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    [connection release];
}

My problem is that there is a leak with the nsmutableurlrequest object. I think i should release it somewhere, but when i try to do so, i get an exec_bad_access. Whereever i try to release it i get that error at the end of the connectionDidFinishLoading method.

EDIT: It looks like i can either release the NSURLConnection object OR the NSMutableURLConnection object.

If i try to remove both of them when i should, i get an exec_bad_access
