65117 Modify Perlscr to incl. Proxy

I have a very short and simple perlscript using HTTP::Headers - HTTP::Request - LWP::UserAgent to contact websites (stored in an external list) incl. logging. I need the script to be changed for using proxy servers stored in an external txt file. The connection via proxy has to be added to the logfile (if connection ok or error). In case proxy is down (refused or not responding) proxy has to be taken out of list and written into a badproxy file. In case of a proxy not working the url that was being checked should be rechecked with the next proxy. Can explain further once we are in contact. Should be quite easy. Looking forward to your offer. Thanks
