Why doesn't 301 redirect htaccess work?

Question

Joomla

Good afternoon. I did an elementary redirect and ran into a problem - it does not work.

Redirect 301 /index.php?productID=1109 http://*****.***/krovlya/polimernaya-krovlya

At the same time, the view redirect
Redirect 301 / https://google.com/
works fine.
Z.Y. The old site was on joomla, the new one on opencart. I was given the task of redirecting some pages of the old site to the new one.

Answer 1

Because in Redirect only url without parameters is taken into account, i.e. will work like this (redirect from /index.php to the new one):
in your case, you need to use RewriteCond and RewriteUrl, like this:

RewriteEngine On
RewriteCond %{QUERY_STRING} ^productID=1109$
RewriteRule ^/?index\.php$ http://*****.***/krovlya/polimernaya-krovlya [L,R=301]

Answer 2

as agreed today, the second one
/? at the end of the url "where" will delete the get request.
