Using // in a RewriteRule

[pr0fess0r]

Hi all
I followed the tutorial here:

http://www.shadow-fox.net/site/tutorial/45-Create-Dynamic-URLs-With-Mod-Rewrite-and-PHP-Functions

to create a rewrite rule so that

http://blah/index.php?id=7&page=4

could be written

http://blah/index//id/7/page/4/

for search engine friendliness, but it's not working. I have a Windows server running Apache, with the following .htaccess file in

http://blah/foo/:

RewriteEngine on
RewriteRule (.*)//(.*) $1.php?parameters=$2

But using the URL

http://blah/foo/index//id/10/

I get a 404 error.

If I use

RewriteEngine On
RewriteRule index/(.*) index.php?parameters=$1

Then

http://blah/foo/index/id/10/

works fine. Can anyone help out a poor n00b?

many thanks

Lucas
