PHP WAMP .HTACCESS如何重写URL？

I've the following URL: http://www.domain.com/content/index.php?filename=download-file.zip&visitorid=abcd&visitorval=xyz

And I want to access this script using the URL as following: http://www.domain.com/content/download-file.zip?visitorid=abcd&visitorval=xyz

I've enabled rewrite_module modules/mod_rewrite.so and I've added an ".htaccess" file to the "content" subdirectory above, but couldn't write the rules to use at the .htaccess file to get the above redirect working.

Thoughts?

Put this code in your /content/.htaccess file:

RewriteEngine On
RewriteBase /sites/some.domain.com/content/

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php?filename=$1 [L,QSA]
