Description: ------------ In the version of PEAR Cache::Lite we have, it is impossible to tell the cache system never to refresh. This is really useful in case of frontend systems that need to cache forever and refresh on-demand. A patch is attached, for Cache::Lite 1.5.2.

thanks, i will consider this for the next version

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
