Cod pentru stergere slash de la sfarsit url?

Remove trailing slash - mai exact.

Nu stiu programare si am incercat zeci de coduri in .htacces.

Ultima versiune este :
Options +FollowSymLinks
# Remove multiple slashes anywhere in URL
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^(.+)/$
RewriteRule ^(.+)/$ /$1 [R=301,L]

Care in mod normal ar trebui sa faca :
- redirect de la non www la www
- elminare multiple slash din url
- eliminare slash multiple din radacina.

Multiple slash nu merge, de bine de rau ma trimite in 404, ceea ce e ok vs duplicate content.

Are idee cineva care sunt codurile corecte/ordinea corecta?

Tks

Din ce am citit pe net...deci nu am testat:

Cod:

---

Options -Multiviews -Indexes +FollowSymLinks
RewriteEngine On
RewriteBase /
DirectorySlash Off

# remove trailing slash
RewriteRule ^(.*)\/(\?.*)?$ $1$2 [R=301,L]

---

-----EDIT
Am testat si cam asa functioneaza la minte

Cod:

---

RewriteEngine On
RewriteBase /
DirectorySlash Off
ErrorDocument 404 http://www.site.com
RewriteCond %{HTTP_HOST} ^site\.com
RewriteRule (.*) http://www.site.com/$1 [R=301,L]

RewriteRule ^([-a-zA-Z0-9]+)$ $1.php [NC,L]
# remove trailing slash

---

Multumesc. Intre timp am decis sa modific site-ul pe wp ca e totusi treaba de programare.
Subiectul ramane insa deschis.
