Oh wow, this is something New for me to look into.

What if the interrupt is line disconnected/closing browser/stop page loading? My program are mainly run thru www web browser, there is no command line execution in concern here. Does the interrupt handler you suggested able to capture this or they are all same?

In my own theory, if possible to capture such interrupt with custom INT handle function, then I should be able to do some cleanup in the function. Eg.

sub INT_handler {
# check for any unfinished jobs
# close all files
exit(0);
}

$SIG{'INT'} = 'INT_handler';

The code above are my own untested modification theory from google search.

    Sorry, but I'm not qualified to answer that question. I suggest you post a new SoPW along the lines of:"What sources of interrupts can affect my perl/CGI script; and what can I do about them?".

      Thanks, I'll do that after I have done some homework. In fact, you already given me some important point of where to look into this matter. It has something to do with SIGPIPE/ connection interrupt.

      Reading thru page http://perl.apache.org/docs/1.0/guide/debug.html section "Handling the 'User pressed Stop button' case", "Detecting Aborted Connections", "The Importance of Cleanup Code" given me great deal of extra understanding of it. Thanks again.
