This maig This is "permanent"

APC

There is magic data storage mechanism based on the Pear APC module and implemented by the class I2CE_MagicDataStorageAPC. It caches data in the memory segment between reqeusts with a timeout of 5 minutes. Data cached by Apache is not cached on the command line.

SysV

There is magic data storage mechanism based on SysV I2CE_MagicDataStorageSysV. It is not available in windows. It creates shared memory segments to cache the data between requests. It's advantage over APC is that the same shared segments can be accessed via the command line. There is no time-out for the data stored. To clear from the command line the shared memory segments

ipcs -m | grep www-data | awk '{print "ipcrm -m "$2}' | sudo bash
