Different page caching folder for different domains

Hi,

I created a multi-domain application, and I wanted to add page caching, how can I tell Rails that it should save each cached page under a subfolder such as public/www.mysite1.com/ and public/www.mysite2.com

If you’re using page caching, then the cached page should located relative to

the root of your website. Thus, if you were to access the index page on both

www.mysite1.com and www.mysite2.com, the you should be able to find an

index.html in the following locations:

URL: www.mysite1.com/index.html On Disk: /rails-app1/public/index.html

URL: www.mysite2.com/index.html On Disk: /rails-app2/public/index.html

Now, if you really want to change the location of the cached pages to use another

directory other than the above, you can do the following:

Moving your Page Cache

First you’d want to add the following to your /config/environment.rb:

`
`

config.action_controller.page_cache_directory = RAILS_ROOT + "/public/cache/"

This tells Rails to publish all your cached files in the /public/cache directory. You would then want to change your Rewrite rules in your httpd.conf to be:

1`
`2`
`3`
`4`
`5`
`

# Rewrite index to check for static`
`  RewriteRule ^/$ cache/index.html [QSA]`
``
`  # Rewrite to check for Rails cached page`
`  RewriteRule ^([^.]+)$ cache/$1.html [QSA]
