When you put a value in memcached, you can set an expiration time.
However, when you increment a value you can not (at least not from PHP) set a new expiration time.
My question: Is the expiration time reset on increment to it's initial value? Or it it unchanged? Or is there another way to regenerate the expiration time?
EDIT:
Both the memcache documentation is vague about this, as well as the PHP documentation
