That works fine.
I would like to allow people to sign up from a page in the www subdomain by tying one request from that subdomain to the main app - www.domain.com/sign_up. The following .htaccess doesn't work, and I can't figure out why:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{http_host} !^www\. [NC, OR]
RewriteCond %{request_uri} sign_up
RewriteRule ^(.*)$ dispatch.fcgi [QSA, L]
Any ideas?
