Subject:	apc_store and apc_fetch between apache processes

Is APC cache memory shared by all apache httpd child processes or does
each httpd process have its own APC cache memory?

If I call apc_add('foo','bar') from httpd child 1
And later call apc_fetch('foo') from httpd child 2 (a different linux
process)
 will the apc_fetch return 'bar' ?

Sorry to post this here (probably not the appropriate venue).  My 
comp.lang.php newsgroup posting went unanswered, and I could not find any 
APC documentation which would answer this question.
