Rails 2.3.2 server restart does not appear to clear fragment cache

After upgrading to Rails 2.3.2 I am now experimenting with Rails caching. I have cache enabled for one action in a few controllers. This seems to work until I restart the server.

After restart, I get Invalid Authenticity token errors on POSTS from pages that were previously cached. I've tried clearing the browser cookies and cache and the problem does not appear to be on the browser side.

I think the default cache store is Memory. I don't see any cached files on the disk.

I can clear the problem by visiting an uncached page on my application and POSTing from there. My cache sweeper expires the cache in that case. After this, everything works since I expire all cached URL's.

Is there a way to definitely clear the Rails cache on server restart?

Also, please confirm that the default cache store is memory. I had assumed that the memory cache would clear automatically on server restart. Maybe my assumptions are not correct.

Thanks.

The following should work for you:

rake tmp:cache:clear

Thus, you might want to invoke the above when you start/restart
your server.

In production, the default global cache is mem_cache_store.

Good luck,
