Re: [SMARTY-DEV] Here it is: Patch for {nocache} support

Cache functionality is the next major project for Smarty, this has been waiting for post-2.5.0 release. There have been lots of discussions on this in the recent past, and I think the most prominent method that stood out was the ability to register a function as cached or non-cached. Then if you wanted the {cache}{/nocache} functionality, you could register a block function called "nocache" that is marked as a non-cached function.
