Mam taki kodzik który uruchamia serwer, w razie kontaktu z przeglądarką pobiera dane z klawiatury i odsyła stronę - ale 2 razy się uruchamia przy jednym wczytaniu strony

I normalnie odczytuje pierwsze zapytanie do serwera, pobiera dane z klawiatury wyświetla je na stronie ale zaraz potem próbuje wczytać drugi raz
jak to zatrzymać, to wygląda jak by przeglądarka podwójne zapytania wysyłała
