Subject Re: [users@httpd] Cookie-Based Rewrite
Date Fri, 10 Mar 2006 12:06:37 GMT
OK, so I got this figured out, and thought I'd post it here for

Rather than putting the cookie rule in a separate .htaccess file in
the demo directory, I put them both in the root:

RewriteCond %{HTTP_HOST} ^$
RewriteCond %{REQUEST_URI} !^/demo/
RewriteCond %{HTTP_COOKIE} phn_demo=([^;]+)
RewriteRule (.*) /demo/%1/$1 [L]

RewriteCond %{HTTP_HOST} ^$
RewriteCond %{REQUEST_URI} !^/demo/
RewriteRule (.*) /demo/$1

It works wonderfully. I just realized I should probably remove the $1
from the second rule, though, as I don't want them going anywhere or
getting 404s if they don't have a cookie. Damned cool voodo.
