php - How to delete memcached key set by another web server -

consider 2 memcached servers, mc1 , mc2 , 2 web servers, web1 , web2, using php memcached library.

$mc = new memcached(); $mc->addserver(mc1); $mc->addserver(mc2);

from web1 next code executes:

$mc->set('abc', 'val'); // key set mc1

later on, web2:

$mc->delete('abc');

from understand on how memcached library works, web2 wouldn't know web1 has set key. how can 1 accomplish this?

right i'm iterating through servers , issue delete on each. i'm thinking there might improve way this.

with multiply servers architecture memcached access (set/get/delete) keys on servers based on hash of key. so, yes - web2 not know deleting on web1. not problem in situation. memcache delete key right server placed before.

please read question: using multiple memcache servers in pool
