$request++;
That's what I do in some handler, and then I log it along with the PID.

This code:
warn request is [.$r.]\n;
yields:
request is [Apache::Request=SCALAR(0x862a9ec)]
I am pretty sure what he is proposing as a solution (something which I have
also done):
Set a normal var to 0 (say in a PerlChildInitHandler)
Then in the PerlHandler increment the normal var
$phase = $r-current_callback;
if ($phase eq 'PerlChildInitHandler')
{
$reqCtr = 0;
}
if ($phase eq 'PerlHandler')
{
$reqCtr++;
}
Or, you could use a note and skip the global scalar.
I don't think mod_perl has direct access to the current count (at least not
in mp1).

Ah! you're maintaining your own counter; I see.
I was looking for this element of Apache's own bookkeeping to be
exposed; I suppose I should have been more specific.
So, not that Bill's solution is unusable to me, let me ask my
question a bit more specifically:
Deep in the guts of http_main.c of Apache's source, I see code like
this:
void worker_main(void)
{
...
int total_jobs = 0;
...
if (max_jobs_per_exe (total_jobs max_jobs_per_exe)) {
/* Reached MaxRequestsPerChild. Stop accepting new connections
* and signal the parent to start a new child process.
*/
ap_start_restart(1);
break;
}
Is this 'total_jobs' exposed somehow via an Apache object? Or do
I need to maintain my own counter, as per Bill's solution?
