I need to delete a file, but the cached files are no longer in the tmp  
folder on the production server. I don’t see them in the shared either.  
I can’t even find anything with the \*nix find command.

Any clues?

Thanks for the help.

I believe cached files are stored in the public directory.

Ooops, I should’ve been more specific. Most of my caching is done via  
caches\_action, not caches\_page which is stored in the public dir.

Chris,

So after some digging around in the source I turned up the method  
“lookup\_store” for ActiveSupport::Cache.

Typing this into console got me the following:

> > ActiveSupport::Cache.lookup\_store  
> > =\> #\<ActiveSupport::Cache::MemoryStore:0x24f9c44 @data={}\>

Also, the documentation in the class points out the following:

# == Caching stores

# 

# All the caching stores from ActiveSupport::Caching is available to be

used as backends for Action Controller caching.

# 

# Configuration examples (MemoryStore is the default):

# 

# ActionController::Base.cache\_store = :memory\_store

# ActionController::Base.cache\_store = :file\_store,

“/path/to/cache/directory”

# ActionController::Base.cache\_store = :drb\_store,

“druby://localhost:9192”

# ActionController::Base.cache\_store = :mem\_cache\_store, “localhost”

# ActionController::Base.cache\_store = MyOwnStore.new(“parameter”)

So, to answer your question, your caches are being stored in memory, but  
you can totally change where you want them to be stored.

Hope that helps,
