The criteria is hard-coded, so you to put beforeRender() something like this:
$this->_criteria = array(‘controller’);
This example will create one cache entry for every controller you have.

I just updated the code and the post to allow the use o $full = true, thank you for this catch.

See ya!

Still haven’t figured put how/where to pass the prefix to your code, but it doesn’t matter that much for me. However, I ran into another more serious problem. When passing true to the “full” parameter in the URL function, of doesn’t take that into account when getting the info from the cache, so it returns the URL without the base address apended. At least I think that’s what happens (I’m using it for sending emails). Suggestions?

Good catch with the double empty, its really a highlighting problem. I’m going to create a ticket for it. Thank’s.

The code as improved in two ways:
1 – You can define a separated cache settings for this. Its named “_app_urls_”. Its mean that you can use FileEngineCache for model caches and so on and use APC for this particular cache. (Take a look on this article Cache duration and configuration tips)
2 – Putting more keys on $this->_criteria you can separate the caches. I’m using $this->_criteria = array(‘prefix’) its mean that will be created two caches: Front-end cache and Back-end (admin) cache.

Thank you for your reply!

In what way, more exactly, is this code improved?

Also line 33 looks funky here: “if (!emptyempty($this->_cache[$key])) {” but it only seems to be the highlighting, plain mode looks fine. Strange.
