Trying to redirect with and without trailing slash

Question

I have moved a blog to a subdomain and on the subdomain all the categories have changed so I want to do a list of 301 re-directs from old domain to subdomain (different hosting).

The problem I am having is adding on the trailing slash so I don't have to list every URL twice.

I tried this in /blog/.htaccess:

RewriteEngine On

#RewriteRule ^(.*)$ http://domain.com/blog/$1/ [L,R=301] 

Redirect 301 /blog/test/ https://new.domain.com/test/
Redirect 301 /blog/example/ https://new.domain.com/example/
(etc...)

This doesn't work though as the browser detects too many re-directs.

What is the proper syntax here?

I also tried:

RedirectMatch /blog/test/?$ https://new.domain.com/test/ [L,R=301] 

But that doesn't seem to work at all.

Solution

Please use bellow syntax

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !example.php
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://example.com/$1/ [L,R=301]

RewriteCond %{REQUEST_FILENAME} !-f makes shure that files that are existing will not get a slash added.

RewriteCond %{REQUEST_URI} !example.php exludes a sample url that shouldn’t be rewritten.

RewriteCond %{REQUEST_URI} !(.*)/$ finally fires when a urls doesn’t contain a trailing slash – this is all what we want. Now we need to redirect these url with the trailing slash:

RewriteRule ^(.*)$ http://example.com/$1/ [L,R=301] does the 301 redirect to the url with the trailing slash appended for us. You should replace domain.com with your url.

Note that this only redirects that one specific URL (unlike the Redirect directive you had initially). For instance, this won't redirect /blog/test/something, if that is a concern?

you might want to add a bit of explanation why this syntax will work
