htaccess根据查询字符串重定向到子域

Question

I searched for similar questions but none of them was applicable to my situation.

What I need to do is redirect from old url's that have specific query string: option=com_virtuemart to a subdomain : http://parts.domain.com

Tried bunch of rules and conds but haven't achieved right redirection. It was always redirecting me to http://parts.domain.com/index.php?option=com_virtuemart

Some of the rules I tried:

RewriteCond %{QUERY_STRING} (^|&)option=com_virtuemart(&|$) [NC]
RewriteRule (.*) http://parts.domain.com/$1 [R=301,L]

RewriteCond %{QUERY_STRING} (^|&)option=com_virtuemart(&|$) [NC]
RewriteRule http://parts.domain.com/? [L,NC,R=301]

And like 50 other rules. What mistakes I'm doing here?

Answer 1

You just needed to combine your rules.

RewriteCond %{QUERY_STRING} (^|&)option=com_virtuemart(&|$) [NC]
RewriteRule (.*) http://parts.domain.com/? [L,NC,R=301]

In the second example, you had not provided the regular expression to match.
