I have a domain with two versions and I need to redirect 1 of the versions
test.example.ca
test.example.ca/en
test.example.ca/fr
I need the first domain test.example.com to redirect to test.example.ca/en anytime someone hits it. but i don't want test.example.ca/fr to redirect to test.example.com/en/fr
this is what I've been trying with no success.
RewriteCond %{HTTP_HOST} =test.example.ca
RewriteCond %{HTTP_HOST} !=test.example.ca/fr
RewriteRule ^(.*)$ https://%{HTTP_HOST}/en/$1 [R=301,L]
I understand the question such that you simply to not want requests to https://test.example.com/fr... to get redirected. So you want an exception.
I'd say this roughly is what you are looking for:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^test\.example\.com$
RewriteCond %{REQUEST_URI} !^/fr
RewriteRule ^ https://test.example.ca/en%{REQUEST_URI} [R=301,L]
Chances are that your question was wrong in a few details, to me it reads as if you were not really precise with your host names. But above should be the correct answer to what you actually asked.
You should implement such rules in the http server's host configuration. If you do not have access to that you can also use a distributed configuration file (".htaccess"). That file should be located in the DOCUMENT_ROOT folder defined for your http host. And you need to make sure that the interpretation of such files is enabled at all (see the documentation for the AllowOverride directive for that).
It is a good idea to start out using a R=302 temporary redirection first. And to only change that to a R=301 permanent redirection once everything works as desired. That prevents nasty caching issues on the client side.
