Hi, I'm getting crazy with htaccess and rewrite rule.. I'd like to understand how it works, I hate it, anyway here's my problem

(really simple for most of you)

My site has one main page index.php. This is the only page, all the others are handled by this one.

I did a simple RewriteRule

RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?page=$1

to do this: http://www.me.ext/index.php?page=VAL -> http://www.me.ext/VAL

but I don't know how create a rule for this

http://www.me.ext/index.php?page=VAL&var1=VAL2&var2=VAL3 etc.

I'd like a final url like: http://www.me.ext/VAL/VAL2/VAL3 etc.

Thanks
