友好网址的Rerite规则 - 不工作

Question

我正在尝试将/healthcare.php简化为/ healthcare，将global_total_office.php简化为/ global

我相信我已经遵循了所有正确的RewriteEngine指令，但是当我转到缩短的URL时，我只得到一个空白的白页。请帮忙！

这是.htaccess文件的完整RewriteEngine部分：

RewriteEngine on

#rewrite rules for friendly urls
RewriteRule    ^healthcare/?$    /healthcare.php    [R=301,NC,L]
