Htaccess: add/remove trailing slash from URL

问题:

My website runs a script called -> WSS wallpaper script

My Problem -> I have been trying to force remove or add trailing slash to the end of my URL to prevent duplicated content and also to clean up my URLs.

I have tried all sorts and tried everything I could think of and loads from the interwebs but no such luck yet! It might be a quick fix but I have looked at it so much I am probably blind to something dead obvious.

So I present you with all my .htaccess code:

DirectoryIndex index.php  RewriteEngine on RewriteRule ^download/([0-9]+)?/([0-9]+)x([0-9]+)/([^/\.]+) image.php?id=$1&width=$2&height=$3&cropratio=$4&download=1 [L] RewriteRule ^file/([0-9]+)?/([0-9]+)x([0-9]+)/([^/\.]+) image.php?id=$1&width=$2&height=$3&cropratio=$4 [L] RewriteRule ^preview/([0-9]+)?/([0-9]+)x([0-9]+)/([^/\.]+) wallpaper_preview.php?id=$1&width=$2&height=$3&name=$4 [L] RewriteRule ^thumbnail/([0-9]+)?/([0-9]+)x([0-9]+)/([^/\.]+)/([^/\.]+)/([^/\.]+)/([^/]+) image.php?wallpaper_id=$1&width=$2&height=$3&cropratio=$4&align=$5&valign=$6&file=$7 [L] RewriteRule ^cat/([0-9]+)?/([^/\.]+)/p([0-9]+) index.php?task=category&id=$1&name=$2&page=$3 [L] RewriteRule ^cat/([0-9]+)?/([^/\.]+)/([0-9a-zA-Z?-]+)/p([0-9]+) index.php?task=category&id=$1&name=$2&sortby=$3&page=$4 [L] RewriteRule ^cat/([0-9]+)?/([^/\.]+)/([0-9a-zA-Z?-]+)-([0-9]+) index.php?task=category&id=$1&sortby=$3&page=$4 [L] RewriteRule ^cat/([0-9]+)?/([^/\.]+) index.php?task=category&id=$1&name=$2 [L] RewriteRule ^tag/([^/\.]+)/([0-9a-zA-Z?-]+)/([0-9]+) index.php?task=tag&t=$1&sortby=$2&page=$3 [L] RewriteRule ^tag/([^/\.]+) index.php?task=tag&t=$1 [L] RewriteRule ^profile/([0-9]+)?/([^/\.]+) index.php?task=profile&id=$1&name=$2 [L] RewriteRule ^profile/comments/([0-9]+)?/([^/\.]+) index.php?task=users_comments&id=$1&name=$2 [L] RewriteRule ^page/([0-9]+) index.php?task=view_page&id=$1 [L]   RewriteRule ^register index.php?task=register [L]  RewriteRule ^lost-password index.php?task=lost_pass [L]  RewriteRule ^links index.php?task=links [L] RewriteRule ^news/item/([0-9]+)/([^/\.]+) index.php?task=news&id=$1 [L] RewriteRule ^news/page([0-9]+) index.php?task=news&page=$1 [L] RewriteRule ^members/([^/\.]+)-([^/\.]+)/page([0-9]+)? index.php?task=member_list&sort=$1&order=$2&page=$3 [L] RewriteRule ^members index.php?task=member_list [L] RewriteRule ^messages index.php?task=messages [L] RewriteRule ^submit index.php?task=submit [L] RewriteRule ^search/([^/\.]+) index.php?task=search&q=$1 [L] RewriteRule ^search index.php?task=search [L] RewriteRule ^submit index.php?task=submit [L] RewriteRule ^r-([0-9]+)?-([0-9]+)? go.php?id=$1&ref=$2 [L] RewriteRule ^r-([0-9]+)? go.php?id=$1 [L] RewriteRule ^([^/\.]+)/([0-9]+)/([^/\.]+) index.php?task=view&id=$2&name=$3 [L] RewriteRule ^news/([^/\.]+) index.php?task=news&name=$1 [L] RewriteRule ^profile/([^/\.]+) index.php?task=profile&name=$1 [L] RewriteRule ^news index.php?task=news [L] RewriteRule ^page/([^/\.]+) index.php?task=view_page&name=$1 [L]   RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^/\.]+)/([0-9a-zA-Z'?-]+)/([0-9]+) index.php?task=category&name=$1&sortby=$2&page=$3 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^/\.]+)/([^/\.]+) index.php?task=view&name=$2 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^/\.]+) index.php?task=category&name=$1 [L]   ## www reslove ## RewriteCond %{HTTP_HOST} !^www\.

Right below the RewriteEngine On line, add:

RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)/$ /$1 [L,R] # 

to enforce a no-trailing-slash policy.

To enforce a trailing-slash policy:

RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*[^/])$ /$1/ [L,R] #

EDIT: commented the R=301 parts because, as explained in a comment:

Be careful with that R=301! Having it there makes many browsers cache the .htaccess-file indefinitely: It somehow becomes irreversible if you can't clear the browser-cache on all machines that opened it. When testing, better go with simple R or R=302

After you've completed your tests, you can use R=301.

To complement Jon Lin's answer, here is a no-trailing-slash technique that also works if the website is located in a directory (like example.org/blog/):

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

For the sake of completeness, here is an alternative emphasizing that REQUEST_URI starts with a slash (at least in .htaccess files):

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

Just don't use %{REQUEST_URI} (.*)/$. Because in the root directory REQUEST_URI equals /, the leading slash, and it would be misinterpreted as a trailing slash.

(update: this technique is now implemented in Laravel 5.5)

Options +FollowSymLinks RewriteEngine On RewriteBase / ## hide .html extension # To externally redirect /dir/foo.html to /dir/foo RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+).html RewriteRule ^ %1 [R=301,L]  RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)/\s RewriteRule ^ %1 [R=301,L]  ## To internally redirect /dir/foo to /dir/foo.html RewriteCond %{REQUEST_FILENAME}.html -f RewriteRule ^([^\.]+)$ $1.html [L]    order allow,deny deny from all satisfy all 

This removes html code or php if you supplement it. Allows you to add trailing slash and it come up as well as the url without the trailing slash all bypassing the 404 code. Plus a little added security.

This is what I've used for my latest app.
