+# Задача
+Реализовать сервер, частично реализующий протокол HTTP, в частности методы GET и HEAD, добиться того, что код проходит предоставленные функциональны тесты. Архитектуру выбрать на свое усмотрение, исходя из вариантов, рассмотренных на занятии. Провести нагрузочное тестирование с помощью ab или wrk
+
+# Запуск тестов
+```
+sh ab -n 1000 -c 10 http://localhost:8080/index.html
+
+wrk -t12 -c400 -d30s http://localhost:8080/index.html
