301 redirect from URL with GET-parameters to the homepage

Question

I have an old website with Joomla 1.5. It has some strange links with GET-parameters, like this:

http://www.primavista.ru/images/stories/catalog/?rand=1186511674
http://www.primavista.ru/images/stories/catalog/?rand=145388433
http://www.primavista.ru/images/stories/catalog/?rand=1553907057
http://www.primavista.ru/images/stories/catalog/?rand=1563973527
http://www.primavista.ru/images/stories/catalog/?rand=1981273478
http://www.primavista.ru/images/stories/catalog/?rand=2139631800
http://www.primavista.ru/images/stories/catalog/?rand=366928750
http://www.primavista.ru/images/stories/catalog/?rand=524689684
http://www.primavista.ru/images/stories/catalog/?rand=569077423
http://www.primavista.ru/images/stories/catalog/?rand=573405687
http://www.primavista.ru/images/stories/catalog/?rand=879649167

I want make redirect theses links to the homepage. I tried some different instructions in .htaccess:

RewriteCond %{QUERY_STRING} ^/images/stories/catalog/?rand=([0-9]*)$
RewriteRule ^(.*)$ https://primavista.ru/? [R=301,L]

RewriteCond %{QUERY_STRING} ^/images/stories/catalog/?rand=(.*)$
RewriteRule ^(.*)$ https://primavista.ru/? [R=301,L]

RewriteCond %{QUERY_STRING} (^|&)(rand)=[^&]+ [NC]
RewriteRule ^images/stories/catalog(/.*)?$ https://primavista.ru/? [R=301,L,NC]

But no one not working. Maybe here someone can help me with this. Thanks

This probably is what you are looking for:

RewriteEngine on
RewriteCond %{QUERY_STRING} rand=\d+
RewriteRule ^/?images/stories/catalog/?$ / [R=301,L]

It is a good idea to start out with R=302 temporary redirections and to only change that to R=301 permanent redirections one you are satisfied with everything. That prevents nasty caching issues on the client side ...

UPDATE: Your comment below indicates that you actually ask to remove the GET parameter in the redirected request, which you never mentioned before...

You can use the additional QSD flag for that:

RewriteEngine on
RewriteCond %{QUERY_STRING} rand=\d+
RewriteRule ^/?images/stories/catalog/?$ /? [R=301,QSD,L]
