Providing you are on a *nix server, if your index page will handle the
get variables to decide which page to present, you can just reroute
using .htaccess with something like this:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^index\.php.*$ [OR]
RewriteCond %{REQUEST_URI} !^images/.*\.(jpg|gif|png)$ [OR]
RewriteCond %{REQUEST_URI} !^cgi-bin/.*$
RewriteRule ^([a-zA-Z0-9_]*)/?$ index\.php?id=$1 [L]
The three conditions are for:
a) avoiding the page redirecting if index is asked for
b) avoiding image requests from your page being redirected
c) avoiding the cgi-bin scripts being redirected
The rewrite rule is one I use myself, you will have to think up what
would be a good one for your url scheme, but this one will just take any
alphanum character (plus the underscore) after the base address
(www.yoursite.com/) and send it as a get variable called id to the
index.php script.
If you don't uneed get variables, you can just use something like:
RedirectMatch permanent ^/.*$ http://www.yoursite.com/index.php
For more information, have a look at some .htaccess tutorials or the
Apache documentation on it.
