mod_rewrite getting a 404 without using a / in the url

[redbrad0]

Posted below is my entire .htaccess file for my site. The problem is if you goto http://www.domain.com/addlisting/ it works fine but if you goto http://www.domain.com/addlisting (without the trailing /) you then get a 404 error page. We all know if someone tells someone to goto a directory on a domain they never end it in a / which is where this problem comes in. What am I missing from my htaccess file that would cause this to happen?

FYI - This happens in all rules set, but I just used the addlisting as its the top rewrite rule.

	Order allow,deny

Allow from all

Scroll down to Trailing Slash Problem

Are you talking about this?

Trailing Slash Problem

Description:
Every webmaster can sing a song about the problem of the trailing slash on URLs referencing directories. If they are missing, the server dumps an error, because if you say /~quux/foo instead of /~quux/foo/ then the server searches for a file named foo. And because this file is a directory it complains. Actually is tries to fix it themself in most of the cases, but sometimes this mechanism need to be emulated by you. For instance after you have done a lot of complicated URL rewritings to CGI scripts etc.
Solution:
The solution to this subtle problem is to let the server add the trailing slash automatically. To do this correctly we have to use an external redirect, so the browser correctly requests subsequent images etc. If we only did a internal rewrite, this would only work for the directory page, but would go wrong when any images are included into this page with relative URLs, because the browser would request an in-lined object. For instance, a request for image.gif in /~quux/foo/index.html would become /~quux/image.gif without the external redirect!

My .htaccess file now looks like below, but when I goto http://www.domain.com/addlisting i get a error but when I goto http://www.domain.com/addlisting/ it works fine. So the line I have bolded (which was just added) did not seem to do the trick.

<Limit GET POST>
	Order allow,deny

Allow from all
</Limit>

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
