Okay, here is my first program to post. I need help making it more efficient and such. Please ignore my not using CGI.PMs HTML shortcuts, I'm still reading up on those.
Anyway, this script uses the query string to select a file and then displays it's contents on a webpage. Only files in the same directory and with certain allowed extensions can be viewed. 
#!perl -w
use strict;
print "Content-type: text/html\n\n";


#Extensions that can be viewed. (Seperated with vertical lines.)
my $ext='pl|css|html|htm|shtm|shtml';


my $request=$ENV{'QUERY_STRING'};
$request=~/([-\w_]+\.($ext))/g;
my $file=$1;
open(SCRIPT,"<$file");
flock(SCRIPT,1);
my @code=<SCRIPT>;
close(SCRIPT);
foreach(@code){
$_=~s/</&lt;/g;
$_=~s/>/&gt;/g;
}
print<<FIRSTPART;
<HTML>

P.S. - This program was made just to help me practice Perl scripting.
