This code will return the size of a file, but it has limitations. It would
require some more testing than I have done to be sure of it's capabilities.
There are 2 examples that work, one using and html file and one using a jpg
file. I know that this code doesn't work for returning php file sizes.
#!/usr/bin/perl
use LWP::Simple;
my @heads = head 'http://www.swjedi.net/index.html';
print "$heads[1] bytes\n";
use LWP::Simple;
my @heads = head 'http://www.swjedi.net/_themes/neon/neobkgnd.jpg';
print "$heads[1] bytes\n";
