.htaccess that redirects to index.html, or to index.php if there are parameters

Question

I am looking for a .htaccess that does the following:

1. For users that visit mydomain.com , the server should return the index.html file from the root.

2. For users that visit mydomain.com/something/ , mydomain.com/anything/123/ , mydomain.com/some%20encoded%20text , etc., the server should return the index.php file from the root and pass the text after www.mydomain.com/ as a PHP $_GET variable.

I tried the WordPress .htaccess :

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

But this redirects everything to the index.php file.

Answer 1

Enable mod_rewrite and .htaccess through httpd.conf (if not already enabled) and then put this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteRule ^$ /index.html [L]

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

Inside index.php you can access $_GET['f'] variable that will give you requested URI.
