How to make an ajax request redirect?

Question

htaccess

There is a link in an ajax request of the form - https://example.com/ru/?wc-ajax=get_refreshed_fragments
It is necessary that a redirect to https://example.com/en/?wc-ajax=get_refreshed_fragments
I tried to write like this, but did not help:

RewriteCond %{HTTP_HOST} ^example.com$
RewriteCond %{QUERY_STRING} wc-ajax
RewriteRule ^$ https://example.com/en/? [R=301,L]

and

RewriteCond %{HTTP_HOST} ^example.com$
RewriteCond %{QUERY} ^wc-ajax [NC]
RewriteRule ^$ https://example.com/en/? [R=301,L]

Answer 1

^$( Only an empty string matches the regex .)
Try this (didn't test it, and I'm new to mod_rewrite myself):

RewriteCond %{QUERY_STRING} wc-ajax
RewriteRule ^ru/(.*) /en/$1 [R=301,L]
