Title: Mirroring Using Apache HTTP Server Version 2.2 (experimental)
license: https://www.apache.org/licenses/LICENSE-2.0
-**These instructions are currently experimental ; not for production.**
-
-If you are using version 2.2 or greater of the Apache HTTP Server for your
-mirror, you can try to mirror using a cached reverse proxy in
-place of rsync. This configuration minimizes resource usage both for you
-and for our servers and also assures that our users can immediately access
-new files.
-
-Before using this configuration, please assure that your server includes
-the modules
-[mod_cache](http://httpd.apache.org/docs/2.2/mod/mod_cache.html) and
-[mod_disk_cache](http://httpd.apache.org/docs/2.2/mod/mod_disk_cache.html).
-Then the following directives should be added to `httpd.conf` either in the
-main server context or inside a `<VirtualHost>` :
-
- CacheRoot /usr/local/apache2/var/apachecache
- CacheEnable disk /apache
- ProxyPass /apache http://www.apache.org/dist
- ProxyPassReverse /apache http://www.apache.org/dist
-
-The directory `/usr/local/apache2/var/apachecache` can be replaced with any
-directory **that is writable by the User/Group specified in httpd.conf**.
-The path `/apache` can be changed as needed for your site. In this
-configuration, the site will be accessed as
-`http://yoursite.example.com/apache/`. You may even replace this with `/`
-if you run your mirror on its own virtual host.
-
-To control disk space usage on your mirror, you should run
-[htcacheclean](http://httpd.apache.org/docs/2.2/programs/htcacheclean.html)
-from cron. Please allow at least 5120MB.
-
-Once this is configured and tested, please notify us using the instructions
-on the [How to mirror](/info/how-to-mirror.html) page.
+**These instructions are no longer available.**
