Apache の RewriteRule を使用して、どのように機能させることができますか:
mydomain.com/webpage.php?name=home_page
簡単に:
mydomain.com/
実際に物理的な index.html ファイルを持っていないのですか?
After clarifying the question in the comments, the poster wants 'http://mydomain.com' to internally redirect to 'http://mydomain.com/webpage.php?name=home_page' (without changing the URL in the browser's address bar). Adding the following to .htaccess should do the trick:
RewriteEngine on
RewriteRule ^$ webpage.php?name=home_page [L]
