Redirecting to different url with similar parameters in hatches

问题

I want to redirect the following strings productdetails.asp?pid=23&cid=1 or productdetails.asp?pid=23&cid=3 pid could be any number I have the following:

RewriteCond %{QUERY_STRING} ^pid=([0-9]+)&cid=1?
RewriteRule ^productdetails\.asp$ /Compare/Roland-Digital-Pianos? [L,NC,R=301]
RewriteCond %{QUERY_STRING} ^pid=([0-9]+)&cid=3?
RewriteRule ^productdetails\.asp$ /Compare/Kawai-Digital-Pianos? [L,NC,R=301]

but for some reason when cid=3 it still rewrites to /Compare/Roland-Digital-Pianos while i want it to go to Compare/Kawai-Digital-Pianos Any help Welcome

回答1:

That is because of misplaced ? in your rewrite condition. In regex ? makes previous group optional which is making 1 or 3 option in your query string.

Use these rules instead:

RewriteCond %{QUERY_STRING} ^pid=([0-9]+)&cid=1(&|$) [NC]
RewriteRule ^productdetails\.asp$ /Compare/Roland-Digital-Pianos? [L,NC,R=301]
RewriteCond %{QUERY_STRING} ^pid=([0-9]+)&cid=3(&|$) [NC]
RewriteRule ^productdetails\.asp$ /Compare/Kawai-Digital-Pianos? [L,NC,R=301]
