Question : how can i make a rewrite rule to read links on the link bar,  if there any???

Hey guys,
im using .htaccess to rewrite my links to make it pretty.
on my script i have a submit that read a link on the link bar above for example

http://www.example.com?action=share&url=http%3A%2F%2Fwww.google.com%2F

I want it to be :

http://www.example.com/share/http%3A%2F%2Fwww.google.com%2F

i used this rewrite rule

RewriteRule ^/(.*)/(.*)?$ index.php?action=$1&url=$2 [L]

when i type in http://www.example.com/share/http%3A%2F%2Fwww.google.com%2F on the urls bar on my browser to test the result i get Error 400 (Bad request).

What am i missing?
Thanks so mush

so lets get tricky thing.

Encode the url portion using base64 and pass to url and decode at the destination page.

It will increase your security too.
