更改永久链接htaccess（不是wordpress）

Question

I want Before any URL's, added a keyword

For example:

my URL:

test.com/news/Selena-Gomez

test.com/news/Jackson

now my keyword is: Biography

And the result is:

test.com/news/Biography-Selena-Gomez

test.com/news/Biography-Jackson

How to 1,000 pages added keyword?

my htaccess :

Options +FollowSymLinks

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]
