Re: [Speedycgi-users] Catching end of process / shutdown handler

[Sam H. <sa...@da...>]

You should be able to do this with a shutdown handler.  The perl
interperter backend is the same whether you use "mod_speedycgi" or
"speedy" as the frontend.

Here's a test script.  Put this in your mod_speedycgi directory and
run it by doing an http request.  Five seconds later, a file named
"/tmp/data" should show up when the backend times out and shuts down.

#!/usr/bin/speedy -- -t5
use CGI::SpeedyCGI;
sub save_data {
    open(F, ">>/tmp/data"); print F "data\n"; close(F);
}
BEGIN {
    CGI::SpeedyCGI->add_shutdown_handler(\&save_data);
}
print "Content-type: text/plain\n\nhello world\n";
