I was certain that normal cgis under Apache2 reacted immediately to
aborts. I was wrong ( As I discovered in my quest to devise a test
case proving you wrong... ;-) )
Ok, we're doing the best we can then. Fine. At least the next guy that
comes along will have this thread to read.
So pseudocode for the magic incantation then seems to be:
while (! $done) {
heavyCalculationBite();
$r->print($msg);
# Eval needed to support < 2.0.6 that dies if $r->connection->aborted
eval {
$r->rflush();
};
if ($r->connection->aborted) {
# Handle user abort
last;
}
}
Thank you so much for your enlightening replies!
