   ## If you want to override the value of the same key then use replace one 
   ns_memcache add key value ?expires? ?flags?

   ns_memcache replace key value ?expires? ?flags?

 Example:

1)
   set check [ns_memcache version "192.168.5.8"]
   print $check

2)
   # store the value for 1 min i.e. 60secs
   ns_memcache set firstkey firstvalue 60

3)
   # Will delete firstkey and then you can define another or add another key instantly
   ns_memcache delete firstkey 

   # But if you delete the firstkey with epxiry then the delted key will be never be added
   # untill the expiry time becomes over.
   # firstkey can only be set after 1 min not before then that
   ns_memcache delete firstkey 60

4)
   # The below will increment the value 3 to what our the value of the key is in the memory 
   ns_memcache incr firstkey 3

5) This one is incomplete one... :( 
   # The below will increment the value 3 to what our the value of the key is in the memory
   ns_memcache decr firstkey


6)
   # Replace the key value with the new one
   # but the value should be set in the memmory first see above the seond example
   ns_memcache replace key value
