You might have some pretty serious problems depending on how your clients firewall is setup. If the proxy server/firewall is set only to allow communication through port 80 (the web server port) and not any other port, you're hosed. SSL normally requires port 443 to be open... if the proxy server blocks all the ports except 80 no amount of Perl will help you.

However, it could be that all you need to do is set the proxy settings in your script using LWP. The key is to use the LWP::UserAgent module. From the docs:

$ua->proxy(...)

Set/retrieve proxy URL for a scheme:

$ua->proxy(['http', 'ftp'], 'http://proxy.sn.no:8001/');
$ua->proxy('gopher', 'http://proxy.sn.no:8001/');

The first form specifies that the URL is to be used for proxying of access methods listed in the list in the first method argument, i.e. 'http' and 'ftp'. The second form shows a shorthand form for specifying proxy URL for a single access scheme.
