On Win32 I use LWP::Simple to fetch files from the web, but sometimes the file is to big and causes my script run to forever, if I cancel the script out before before it's finished, the temp file I am writing gets write protected. If I run the script again, on a smaller file, it uses the data from the last session plus the new pages data. Does any have a solution for checking the file size first before grabbing it and putting it into a variable? Or if the script is taking to long to process the data, to quit and unlink the temp file.I AM NEW TO PERL, so don't everybody laugh at one time. Here is my code 

use LWP::Simple;

if ($ENV{'QUERY_STRING'}) { $buffer = $ENV{'QUERY_STRING'}; }
else { read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'}); }
@pairs = split(/&/, $buffer);
foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$value =~ s/\n/ /g;
$FORM{$name} = $value;
}

print "Content-type: text/html\n\n";

$URL = $FORM{'url'};
$page = get($URL);
$page =~ s/\s+/ /g;

# I do more with the $page varaible later but I break it off here.
# Strip most of the HTML, <script>, <style> and punctuation.
# I think it's greedy. Any help? I perfer without perl module?

$break = $page;
$break =~ tr/A-Z/a-z/;
$break =~ s/&nbsp\;/ /g;
$break =~ s/<s.*?<\/s.*?>//igs;
$break =~ s/&lt\;//igs;
$break =~ s/&gt\;//igs;
if(!($break)) { &error; &print_footer; exit; }
&print_main_header;
($text = $break) =~ s/<(\/|!)?[-.a-zA-Z0-9]*.*?>//g;
$text =~ s/[,.?':!"@#\$\%&*()_|\/\-=+\^~`\{\}\[\]\\]//g;
$text =~ s/\s+/ /g;
@text = split(/\s/, $text);
