Apache .htaccess: How to remove question mark from URL if not `?id=(.*)`?

Question

How to make .htaccess to remove question mark from URL if not ?id=(.*)?

# Rewrite for ?id=(.*)
RewriteCond %{Q         


        

Answer 1

Does this work?

RewriteCond %{QUERY_STRING} ^.+$
RewriteCond %{QUERY_STRING} !^id=
RewriteRule ^(.*)$ $1?%1 [R=301,L]

Tip: during your testings, use 302 redirections instead of 301, as 301 redirections are stored by browsers. You can finally switch to classic 301 when you are done testing.
