How to redirect all requests to index.php and keep the other GET params?

Question

Here's what I've got so far:

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !index.php
RewriteRule .* index.php?url=$0 [L]

But when I go to soemthing like /a?b=c and then inspect the GET params, I only get a for url, and b is lost. How can I retain that?

How about using the FallbackResource directive: "Define a default URL for requests that don't map to a file"

<Directory /web/example.com/htdocs/blog>
    FallbackResource /index.php
</Directory>

That way you don't have to call the modRewrite module on every request.
