url rewriting for multiple directories

[eruna]

I'm trying to make site.com/category/sub-category
redirect to www.site.com/category/sub-category

This is what I have so far:
RewriteCond %{HTTP_HOST} ^site\.com$ [NC]
RewriteRule ^(.*)$ http://www.site.com/$1 [R=301,L]

It works for the second level (site.com/category) but not the third (site.com/category/sub-category).

How would you modify this to work for the third level?

Thank You E

Fortunately the Apache documentation talks about this exact situation.

Hi eruna

First, WELCOME to SitePoint!

I'm trying to make site.com/category/sub-category
redirect to www.site.com/category/sub-category

This is what I have so far:

PLEASE wrap your code in [code]...[/code] tags as that preserves the code when quoting for a reply.

RewriteCond %{HTTP_HOST} ^site\.com$ [NC]
RewriteRule ^(.*)$ http://www.site.com/$1 [R=301,L]

It works for the second level (site.com/category) but not the third (site.com/category/sub-category).

How would you modify this to work for the third level?

Thank You E

Your code is fine as is (although you should be warned about the EVERYTHING atom).

[standard rant #1]

The use of "lazy regex," specifically the EVERYTHING atom, (.*), and its close relatives, is the NUMBER ONE coding error of newbies BECAUSE it is "greedy." Unless you provide an "exit" from your redirection, you will ALWAYS end up in a loop!

RewriteEngine on
RewriteCond %{HTTP_HOST} ^site\.com$ [NC]
RewriteRule .? http://www.site.com%{REQUEST_URI} [R=301,L]

You could, perhaps, ensure that mod_rewrite is not in the comment mode by starting with RewriteEngine on and not using (.*) to capture text already available in the {REQUEST_URI} string but you already have an escape from the loop generally created by (.*) so no problem - it WILL capture everything in the path-to-file and simply repeat forcing the www.

Since the OP *did* provide an exit, and did *not* use (.*) in error, this rant seems to be unwarranted.

Jeff,

Did you read my post? It was provided as a warning (to the OP and others).
