Redirect with .htaccess not working correctly when missing / in the end

Question

I've Wordpress site with WPML installed. I've done 2 things recently:

• Move HTTP only to HTTPS only
• Move http://domain.pl to https://domain.xyz (English)
• Move http://domain.pl/pl to https://domain.pl (Polish)

This is done to improve SEO. However while I got that working without much problem using:

 # BEGIN HTTPS
 <IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteCond %{SERVER_PORT} ^80$
 #RewriteCond %{HTTPS} !^on$
 #RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R=301,L]
 RewriteRule ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
 </IfModule>
 # END HTTPS
 # BEGIN WordPress
 <IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteBase /
 RewriteRule ^index\.php$ - [L]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
 </IfModule>

 # END WordPress

In apache.conf file ServerName domain.xyz, ServerAlias domain.pl www.domain.pl and so on. I'm having problems with most of my old blog posts that are around the internet in different forms. For example:

• This little entry http://domain.pl/email-address-policy/ redirects properly to https://domain.xyz/email-address-policy/
• This little entry http://domain.pl/powershell-write-host doesn't. It simply goes to https://domain.pl/powershell-write-host which is 404 and that's it.

It seems that last / is making huge difference.

I've planned to add all redirects in even direct form 1 to 1 to new domain but since it's partially working, partially not I'm kind of lost... and I am not sure how I could translate them correctly.

EDIT:

I've tried multiple options, even one that supposedly rewrites all links to end with / and it still fails.

# BEGIN HTTPS
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#RewriteCond %{SERVER_PORT} ^80$
#RewriteCond %{HTTPS} !^on$
#RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R=301,L]
#RewriteRule ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
#RewriteRule ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
#RewriteRule ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} !^on$
#RewriteRule (.*) https://evotec.xyz/$1 [R=301,L]
#RewriteRule (.*) https://%{SERVER_NAME%}/$1 [R=301,L]
#RewriteCond %{REQUEST_FILENAME} !-f
#RewriteCond %{REQUEST_URI} !(.*)/$
#RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1/ [L,R=301]
#RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteCond %{REQUEST_FILENAME} !\.(gif|jpg|png|jpeg|css|js)$ [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1/ [L,R=301]


</IfModule>
# END HTTPS

Another update:

• https://domain.xyz/url-is-here - works correctly
• https://domain.xyz/url-is-here/ - works correctly
• https://domain.pl/url-is-here - doesn't work, isn't convered to https://domain.xyz/url-is-here/
• https://domain.pl/url-is-here/ - convers correctly to https://domain.xyz/url-is-here/

So it's not entirely not working for all slash vs non-slash. It's more about translation of some sort that doesn't happen if it points to old domain.

I've tried using Redirect Checker to see how it works (on proper example) but I can't make any meaning from it.

http://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1 301 Moved Permanently https://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1/ 301 Moved Permanently https://evotec.xyz/hub/scripts/office365-addbulkemailaddressses-ps1/ 200 OK

• Check of http://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1/

• Check of https://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1

https://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1 404 Not Found

The more options I try the weirder it gets. While the RedirectChecker seems to be showing one thing ... browser is behaving a bit different and doesn't work for the first entry anyways causing 404 straight away

Edit:

If I leave only "Wordpress" data following is true:

• http://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1 gets 404 http://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1 exactly as is
• http://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1/ gets https://evotec.xyz/hub/scripts/office365-addbulkemailaddressses-ps1/
• https://evotec.pl/hub/scripts/office365-addbulkemailaddressses-ps1 gets 404 exactly as is

It only works properly if i use the correct/new domain then all works properly:

• https://evotec.xyz/hub/scripts/office365-addbulkemailaddressses-ps1
• https://evotec.xyz/hub/scripts/office365-addbulkemailaddressses-ps1
• http://evotec.xyz/hub/scripts/office365-addbulkemailaddressses-ps1
• http://evotec.xyz/hub/scripts/office365-addbulkemailaddressses-ps1/

I guess if I can't redirect it, i will leave it as it is and just give up.

Answer 1

I've actually solved it by using SEO Redirection Premium plugin for Wordpress.

It's able to redirect broken links without /. In this case I've done it manually but I'm working on a way to do it in more global way with Regex. Just need to find proper one.
