ZF-4593: "cache_id_prefix" is prepended twice in Zend_Cache_Core::save() method if "write_control" option is enabled (and data fails integrity check)

Issue Type: Bug Created: 2008-10-13T19:58:12.000+0000 Last Updated: 2010-01-09T07:40:46.000+0000 Status: Resolved Fix version(s): - 1.7.0 (17/Nov/08)

If user has "write_control" enabled (default setting) for a Zend_Cache_Core object and they also set a "cache_id_prefix", then the "cache_id_prefix" will be prepended twice when removing the cache entry (when "written and read data do not match").

The problem seems to be on line 375 of Standard_Library/trunk/library/Zend/Cache/Core.php:r11143?
