    предыстория в том, что был полностью кастомизированный sharepoint. Со своими мастер страницами, стилями, страницами и т.д. Нужно было уменьшить вес страниц вырезав ненужные скрытие поля со страницы и чтобы стандартные css, js тоже не грузились

    Тема интересная, для меня актуальная, но поскольку я не в курсе предыстории - непонятно: что вообще делает этот модуль и как его использовать? Жестко оптимизировать страницы очень бы хотелось...
