Now we are talking! This 'CGI_APP_RETURN_ONLY' mode should be documented.
I tried this and it works perfectly. In fact, it is sufficient to set
this flag off for this particular method and not to bother with return
$output:
sub method{
my $subapp = Subapp->new();
$ENV{CGI_APP_RETURN_ONLY} = 0;
$subapp->run();
}
A question remains open, how will this behave with Fast CGI. If I
initialize MyCGIApp outside the FactCGI loop, this flag will, probably,
remain off for other run modes as well. I will have to turn this flag on
and off in each run mode.
Thanks for the fruitful discussion!
