Specfic Question Regarding CI Caching

[eluser]dimensionmedia[/eluser]
This will probably be a stupid question, but at least it should be easily answered.

Say I have a page like:

http://www.xyz.com/index.php/feeds/json

I know that view can be cached but does CI also cache the variables/uri, say like:

http://www.xyz.com/index.php/feeds/json/feed1/10
http://www.xyz.com/index.php/feeds/json/feed2/20
http://www.xyz.com/index.php/feeds/json/feed3/5

etc.

Does all of those get cached or is it just one file?

Hopefully this makes sense. I'm looking to cache output like this.
