I have a domain dedicated for my local server (.dev), and an .htaccess file which redirects requests like http://folder.dev/subfolder/ to /htdocs/folder/subfolder. It works great and all, except for one minor issue. When I have the Directory Listing enabled, I can access all the folders, subfolders and files properly, except when I click on the Parent Directory link, which, for example, should lead to http://folder.dev, but redirects to http://folder.dev/folder/ and consequently throws 404 not found. Similarly, if Parent Directory should link to http://folder.dev/subfolder/, it links to http://folder.dev/folder/subfolder/. Here's how my .htaccess looks like:

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} !(/$|\.)
RewriteRule (.*) %{REQUEST_URI}/ [R=301,L]
RewriteCond %{ENV:REDIRECT_SUBDOMAIN} =""
RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9][-a-z0-9]+)\.dev\.?(:80)?$ [NC]
RewriteCond %2 !^www|ftp|mail|pop3|localhost$
RewriteCond %{DOCUMENT_ROOT}/%2 -d
RewriteRule ^(.*) %2/$1 [E=SUBDOMAIN:%2,L]
RewriteRule ^ - [E=SUBDOMAIN:%{ENV:REDIRECT_SUBDOMAIN}]

Apart from that one thing, everything else works fine (e.g. relative links in documents etc.)
