I would point out that it's a _bad_ design to have Zend_Cache_Core make
this assertion. This restriction makes it impossible to interoperate
the cache with other systems that don't have a similar restriction on ID
space. It would be better if this was left to the Backend
implementation to validate, potentially via a
Backend->_validateIdOrTag(...).

Hi all,
I am using a caching identifier based on the URL. But I'm getting
strange effects: when accessing a URL I see the cached version of
*another* page.
This is the code I'm using for the cache identifier.
$cache_identifier = ereg_replace("/", "_", $_SERVER['REQUEST_URI']);
$cache_identifier = ereg_replace(".", "_", $_SERVER['REQUEST_URI']);
$cache_identifier = preg_replace("/([^a-zA-Z0-9_-])/", '', $cache_identifier);
I added that last line because I was getting errors saying that the
cache identifier could only have a-z and _- characters.
Any thoughts on how to improve this would be very welcome :)
Thanks!
Peter
