How can I specify the location of the fragment cache?

I am using fragment caching - the cache gets stored under RAILS_ROOT/ tmp/cache/www.mysite.com but if someone goes to http://mysite.com (no www) then, a *second* cache gets stored at RAILS_ROOT/tmp/cache/ mysite.com - from this point on, the cache is hit at both URL locations but I end up with 2X the DB hits and 2X over-the-wire web service calls etc I really need.

This is turning out to be really really expensive. How can I avoid this?

Any ideas?

Not a solution to your problem directly, but you may want to consider 301 redirecting all requests to mysite.com to www.mysite.com.

I know that Google will punish your page rankings if it sees the same content in multiple domains...

As a side effect it would also solve your problem..

That's an idea that would have the side-effect of solving my problem yes, but I don't believe Google will punish PR between www and a plain site.com. As you say multiple domains: perhaps between alpha.com and beta.com if there's exactly the same content, then... maybe.

You may be right... now that I think about it our problem was the individual hostnames vs www.

It definitely punished us for that.

You can ensure they always visit the non-www version of your domain name. Here's an Apache rewrite rule for that:

RewriteCond %{HTTP_HOST} !^mysite.com$ [NC] RewriteRule ^(.*) http://mysite.com/$1 [L,R=301]
