Hello all,
I'm currently trying to put a little "search engine" together for
a small web site, basically searching through a bunch of files for
matching keywords.
As I want a Progress Page while the script is doing its work, I show
a page while the script is searching (had to use $| to achieve) and
store the results in a DBM.
So when the search/progress script is finished I activate a JavaScript
doc.location command to call the script again with diff params, thus
reading the results DBM and outputing page by page.
What I want to do is... put a "kill time" of say 20 mins on the DBM file
so that it gets tidied away. So...
$child = Fork() {
some code to Sleep(20 mins);
then Unlink(results DBM);
}
What if the client is still accessing the search results at 20 mins?
I read through PerlDoc perlfork and it recommends not Kill()ing Children.
Can my script, while requests for result pages rain down, communicate
with the $child (richkid ;o), thus sustaining the $child's life?
Probably not the most practical way to achieve my objective,
but I'm not the best at this programming lark. :o)
TommyGun.
