http - Does apaches keep alive time-out reset every time a request is received?

The title of this question is pretty self explanatory, but:

Does apaches keep alive timeout reset (as in, start again) every time a request is received?

So for example, assume we have a 60 second keep alive timeout:

Second 0 - First request recieved, keep alive starts - Timeout currently 60 seconds

Second 10 - Next request recieved, keep alive reset - Timeout currently 60 seconds

OR

Second 0 - First request recieved, keep alive starts - Timeout currently 60 seconds

Second 10 - Next request recieved, keep alive does not reset - Timeout currently 50 seconds

Thanks.
