65 Данный модуль объявляет только интерфейс, тоесть в нем есть заглушки для функций
c6e90e02dd17 renamed Lib->lib
cin
parents:

66 которые необходимо реализовать.

68 Для создания класса, который может быть использоваться для создания Web-ресурсов
c6e90e02dd17 renamed Lib->lib
cin
parents:

69 нужно унаследовать данный интерфейс и реализовать его методы.

75 Выполняет операцию над ресурсом и возвращает результат ее выполнения.
c6e90e02dd17 renamed Lib->lib
cin
parents:

76 Результатом может быть произвольный объект, который будет передан по цепочке
c6e90e02dd17 renamed Lib->lib
cin
parents:

77 обработчиков приложения для формирования ответа вервера, либо
c6e90e02dd17 renamed Lib->lib
cin

78 C<IMPL::Web::HttpResponse>, который описывает (не обязательно полностью) ответ.
c6e90e02dd17 renamed Lib->lib
cin
parents:

79 В любом случае результат будет передан далее в цепочку обработчиков и может
