For one, you don't need both of those patterns at the top, if you just replace

$text =~ s/$target/$replace/;
$text =~ s/$target2/$replace/;
[download]

with

$text =~ s/$target/$replace/i; # Case-insensitive
[download]

Second, I'd look at letting Perl's -i and -p flags do all your editing in place for you. It takes care of all the globbing, the reading the file, etc etc etc.

For instance, your code could simply be (rough and untested):

#!perl -i~ -p

BEGIN {
$/ = undef;
$target = blah blah blah;
$replace = blah blah blah;
}

s/$target/$replace/ig;
[download]

And you'd just call it as:

myprog.pl *.asp
[download]

Perl has some very powerful, very common idioms to do this most common of text transformations. Take advantage of them when you can.
