如何编写.htaccess重定向以查找所有号码？

Question

I'm trying to figure out a regular expression that will find some numbers in a URL and use them in the URL I redirect to.

Redirect 301 /page.php?id=95485666 http://test.com/profile/info/id/95485666

i was thinking maybe

Redirect 301 /page.php?id=([0-9]+) http://test.com/profile/info/id/$1

but it doesn't seem to work

Also, if I do a 301 redirect, how long do i have to keep the code in the .htaccess file? when is Google gonna figure out that the new link is the good one?

Answer 1

You can't match against the query string in the Redirect directive (nor in a RedirectMatch / RewriteRule either). You need to use mod_rewrite's %{QUERY_STRING} var:

RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)id=([0-9]+)($|&)
RewriteRule ^/?page\.php$ http://test.com/profile/info/id/%2? [L,R=301]

Answer 2

Well I guess the syntax is incorrect. Try this:

RewriteRule ^page.php?id=([0-9]+)  http://test.com/profile/info/id/$1  [R=301,L]
