Попробуйте подумать над асинхронным подходом. Время от времени выдаются запросы на подгрузку данных, но основная программа ничего не ждет, а продолжает работать дальше. Просто, пока данные не загрузились, соответствующие части страницы/формы юзеру недоступны (спрятаны или, лучше, деактивированы - disabled). Но со всем остальным юзер может продолжать работать. По завершении загрузки массива "транспортный агент" уведомляет "заказчика", что "товар" прибыл. Например, вызывает callback-функцию, являющуюся одним из аргументов запроса. По дороге наверняка появится много технических проблемок, например, как аннулировать запрос, результаты которого уже не нужны. Как показать пользователю, что программа не висит, а работает, и сколько ему осталось ждать. И тому подобное. Можно сделать и очень красивые штучки, скажем, предикторы, которые оценивают ситуацию и заранее выдают запросы на данные, которые с высокой степенью вероятности вскоре могут быть затребованы. При грамотной реализации страничка даже с весьма объемными данными может просто "летать" ... спустя 13 часов [обр] Дмитрий Котеров [досье] именно так я и сделал (см. второй способ). Вы правы: это - асинхронный алгоритм, и он менее удобен, чем синхронный. Тогда предлагаю продолжить именно про асихронный способ, раз он единственно возможный. Итак, проблема N1: как определить, что CGI-скрипт, загружающий данные в каком-нибудь IFRAME, неожиданно завершился - например, при обрыве связи?.. Сейчас у меня стоит тайм-аут на 10 секунд, а скрипт в середине данных периодически вызывает функцию alive(), сбрасывающий таймер тайм-аута. Как Вы понимаете, это не лучший выход: 10 секунд - довольно

At the first assembly of first-year students I at last have got acquainted with the group and have seen the head. At us the group has stolen up good and amicable (as it has appeared in a consequence). The first month has flown by imperceptibly. During the first session there were many emotions and experiences, but it has been handed over without debts and three. Then on results of the first session the grant was received only by 4 persons among whom there I was also. After 3 rates has gone under the preferential permit to Crimea for 10 days in the summer. It was remarkable rest in cheerful campaign. Also during the training has had time to fly in the winter of 2005 to Egypt and to visit in the winter of 2006 Prague. Both trips have brought weight of impressions and desire on it to not stop. During same time my test book, as they say, has started " to work on me ". In each session I passed a maximum one examination, the others received the automatic device. On 4 rate in 8 semester both course works I did in the individual order. Also in it a semester I have started to work part time as the laboratorian and worked in native dean's office where I continue to work for today. But ahead there were graduation examinations. With greater experiences and the strengthened preparation they have been handed over perfectly well. As a result I have received the bachelor's degree with distinction. In the beginning I knew 4 rates, that I shall go to a magistracy. So it also has turned out. On amusing coincidence of circumstances my work in dean's office for that time was distribution of bachelors to experts and masters. So I of the first learned all news and did not worry for receipt. To sports in the life I have the direct attitude. From the second rate I am engaged in section of badminton where has reached the certain results. Participated in student's competitions and I have 3-rd category. It at the given vital stage the basic my hobby. The theme masters works " the Subsystem of the operative analysis images of steel in conditions MMW " ISTIL (Ukraine) " has arisen not casually. Both my industrial practices passed on the Mini Metal Works " ISTIL (Ukraine) ", but their theme was work with databases. During that moment I was interested with works on recognition images. It also has defined my theme masters works. As the analysis images of metal is responsible for quality assurance of let out production and for conformity to requirements of the customer. Last argument was that fact, that at a factory the analysis has not been computerized. In 1993 I have gone to school - in school №32 which too was near to the house. The class at us was unusual, children there selected on preliminary interview. In primary classes I had a strict teacher. It has imparted to me discipline. I began to go to an art circle. Since then drawing for ever became my hobbies. At school I have studied only 7 classes. And then I have acted in Donetsk Technical Liceum. The quite good group there has stolen up. And studies it was more interesting than at school. In 9 class I have gone to study to play on a guitar. And as a result has left musical school at once on two tools. In a consequence music became for me an outlet, my calm. During study in liceum went on Olympiad on the physicist and year on days off visited a class of physics at school " Erudite ". Since then the physics became for me not such and a complex subject. But the most interesting subject in liceum became for me astronomy. There was in it something mysterious... In 11 class has gone to study in driving. And as result - in May, 2003 has received a driving licence of a category B on automobile transport. During study in liceum we often went to have a rest all family in Svyatogorsk in a boarding house from university. I very much like to travel.
