# Apache configuration example for Varnish-behind-Apache setup

# Include the following in the Apache config like so:
#
#   Include ${buildout:directory}/etc/httpd-vhost.conf
#
# Or copy/paste into the relevant VirtualHost block
# or into the default host if not using VirtualHosts.


# The main domain
<VirtualHost *:80>
  ServerName ${apache-vhost:hostname}
  RewriteEngine On

  # Remove trailing slash to avoid duplicates in caching proxy,
  # 1) for search engines, redirect to normalized version
  # 2) for everyone else, just strip the trailing slash
  RewriteCond %{HTTP_USER_AGENT} ^Yahoo.* [NC,OR]
  RewriteCond %{HTTP_USER_AGENT} ^Googlebot.* [NC,OR]
  RewriteCond %{HTTP_USER_AGENT} ^msnbot.* [NC]
  RewriteRule ^/(.*)/$ /$1 [R=301]
  RewriteRule ^/(.*)/$ /$1

  RewriteRule ^/(.*) http://${apache-vhost:backend}/VirtualHostBase/http/${apache-vhost:hostname}:80/${apache-vhost:zope-path}/VirtualHostRoot/$1 [P]

</VirtualHost>


# Additional domains:
# Avoid the use of the ServerAlias directive in the main domain VirtualHost
# container as this tends to undermine the ability of external search engines
# to accurately assess page uniqueness. Instead perform a 301 redirect like so.
<VirtualHost *:80>
  ServerName www.${apache-vhost:hostname}
  ServerAlias *.${apache-vhost:hostname}
  RedirectPermanent / http://${apache-vhost:hostname}/
</VirtualHost>
