  You shouldn't need to do that.  The sqlcounter module has supported 64-bit counters since 3.0.4, in 2014.

  Yes, because Session-Timeout is a 32-bit integer.

  If you're doing to put values larger than 4G into a 32-bit integer, it won't work.

  If you're going to limit bandwidth by putting bandwidth values into Session-Timeout, it won't work.

  The sqlcounter module supports 64-bit values just fine.   One issue, though is that the module is made to count *time* not *bandwidth*.  All of the documentation and examples show it counting time.  And when you test it, you see the module setting Session-Timeout.  *Not* any bandwidth limitation.

  So again, what are you trying to do?  You've posted a configuration here, but you're not really describing the problem.

  Are you trying to limit bandwidth that the users can download?  Did you *READ* my previous response which explained the problem with that?
