URL 的[網路標準]（https://www.w3.org/TR/WD-html40-970708/htmlweb.html）是有區分大小寫的，畢竟目前為止約有 80% 的網站都是使用 Unix-like 的作業系統架設的，而 Unix-like 作業系統中，是會區分大小寫的。那麼我們要如何讓架設在 GitHub Pages 的 Jekyll 網站，能支援不區分大小寫的網址呢？
Jekyll 本身沒有支援相關的設定，但是你可以透過 jekyll-redirect-from 套件來處理這個問題。
但這個方式有點麻煩，要在每個頁面都加上相關設定。
透過 GitHub Pages 的 404.html 機制，好像挺不錯的。
只要在你的網站中提供 404.html 檔案，當 GitHub Pages 找不到相關的網址（URL 大寫的網址）時，就會自動導向到 404.html 這個檔案。然後我們在這裡去處理相關的路由導向即可。
以下程式碼是以本部落格為例，使用 site.posts 取得所有網頁的 URL，然後和當前的網址進行比對，找到正確的網址做導向。

這樣就可以讓 GitHub Pages 支援不區分大小寫的網址了。
