Pretty URLs on single page

Permalink
I'm trying to figure out how to add pretty URLs to my single page. Using the following thread,http://www.concrete5.org/community/forums/customizing_c5/url-rewrit... I came up with this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteRule ^object/(.*)$ index.php?cID=122&street=$1 [QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

I also added the following line to config/site.php:

define('URL_REWRITING_ALL', TRUE);

But it still doesn't work. Point of notice is that this site is not in document root but in /c5.

Can somebody explain to me how to enable pretty URLs for my single page?

Thanks in advance!
