 New Comment:

To get a file info you need both id and group information, so I suggest
added both as parameters to lasModified.
Your second request I believe is part off your logic and not part of the
package.
get the age information and recreate the cache in a same method make
this method a lot specify
use lasModified method ( if the patch was accept) and then, if it has
invalid, recreate it.

The documentation for lastModified() is lacking, so assuming it doesn't
do this already (i've not checked), this feature should be added as
standard.

Description:
------------
Hi,

I'd like to suggest that the Cache_Lite::lastModified() take a new
arguement, which is the id of a cached object.  The return value would
be the same as currently defined, though if the id did not exist, it
should return -1, or some other error code.

This would allow me to pre-populate my web site with data which takes a
long time to generate, and yet easily query the cache to see if I need
to re-generate the output.

Another thought would be to extend some of the other existing methods to
take a datestring which they check the cache file age against.  If the
cache is older than the date string, return false (and clear that entry)
otherwise just return the cached entry.

This could be:

  Cache_Lite_Output::start(  string $id , string $group = 'default' ,
boolean $doNotTestCacheValidity  = false, int older = '0')

where it checks if the age of the cached file is less than 'older' and
returns False if true.
