Rewrite Query String

Question

I have this URL:

oldsite.com/profile.php?uid=10

I would like to rewrite it to:

newsite.com/utenti/10

How can I do that?

I wrote this:

RewriteCond %{QUERY_STRING} ^uid=([0-9]+)$ RewriteRule ^profile\.php$ http://www.newsite.com/utenti/$1 [R=301,L]

But $1 match the full query string and not just the user id.

Answer 1

"$1" matches the first pair of brackets on the same line (the RewriteRule); you need "%1", which matches the first pair of brackets on the /previous/ line - the RewriteCond:

RewriteCond %{QUERY_STRING} ^uid=([0-9]+)$ RewriteRule ^profile\.php$ http://www.newsite.com/utenti/%1 [R=301,L] 

A better way would be to do it with only 1 line (a RewriteRule), but you can't do that if the uid is in the QueryString.

Answer 2

<IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{SERVER_NAME} ^oldsite.com$ RewriteCond %{QUERY_STRING} uid=([0-9]+) RewriteRule ^/profile\.php http://newsite.com/utenti/%1 [NC,R=301,L] </IfModule> 

the point is to use %1, not $1
