Shell Programming and Scripting

Hi,

I have to connect to online site and download some data from the online site but sometimes the site which i have to connect will be busy
or it will not be working in such a case i have to connect atleast 3 times and try to download the data.

I tried like this:

Code:

use CGI::Carp qw(fatalsToBrowser);

$url="http://www.xyz.com";

$ua = new LWP::UserAgent;

$tries=0;

eval
{
$response=$ua->get($url);
};warn $@ if ($@);
if ($@) {
         die "Server error: $@.  Try again later" ;
         $tries++;
	 if($tries == "3")
	 {

		print "\nstop connecting\n"
	 } 
     }

Actually i am stuck up here if there is any error it is not displaying i.e its not
entering if($@) block . How to reconnect again???

Basically i have to reconnect and download the data when the site is not working.

How to reconnect to the site and download the data???


Any suggestions ???
