        NSURL *url = [NSURL URLWithString:[[NSString alloc] initWithFormat:[NSString stringWithFormat:@"http://%@:%d/stuff.cgi", _host, _port]]];

        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url 
                                                               cachePolicy:NSURLRequestUseProtocolCachePolicy

        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding ]];
        [request setValue:[NSString stringWithFormat:@"http://%@/stuff.php", _host] forHTTPHeaderField:@"Referer"];
        [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
        [request setValue:@"XMLHttpRequest" forHTTPHeaderField:@"X-Requested-With"];
        NSArray *availableCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://%@", _host]]];
        NSDictionary *headers = [NSHTTPCookie requestHeaderFieldsWithCookies:availableCookies];
        [request setAllHTTPHeaderFields:headers];
        NSLog(@"headers: %@", [request allHTTPHeaderFields]);
        NSURLResponse *response;

Solved, just specifie length

[request setValue:[[NSString alloc] initWithFormat:@"%d", [params length]] forHTTPHeaderField:@"Content-Length"];
