Webアクセスを日本国内に ゆるめ に制限する

Last updated at Posted at 2017-10-13

きっかけ

.htaccessに2000行書くとApacheの処理が何秒遅くなるか測ってみた | 編集長ブログ―安田英久 | Web担当者Forum さんによると
.htaccessに2200行ほど書くと1リクエストあたり12ミリ秒の遅延になった
(中略)
(ディレクティブによる違いはあるかもしれません)

IPアドレスで日本国外(海外/外国)からのアクセスを制限する.htaccess CGI's さんから 4137行のhtaccessをダウンロードした場合、
20ミリ秒程度の遅延が見込まれる。

また、行が多すぎてメンテナンスやどこで引っかかったのかチェックがし辛い。

やらないよりマシ的なの作ってみた

IPアドレスで日本国外(海外/外国)からのアクセスを制限する.htaccess CGI's さんから htaccessをダウンロードして以下実行

93行
cat htaccess | cut -f 1 -d "." | cut -f 3 -d " " | uniq

.htaccess (やらないよりマシ的なの)

.htaccess
# Denied all access to the beginning
order deny,allow
deny from all

# allow bot (Slurp=yahoo)
SetEnvIf User-Agent ”Googlebot” allowbot
SetEnvIf User-Agent ”msnbot” allowbot
SetEnvIf User-Agent ”bingbot” allowbot
SetEnvIf User-Agent ”Slurp” allowbot
allow from env=allowbot

# localhost
allow from ::1
allow from 127.0.0.1
