Re: SSL.PM question
Thanks for the response and your suggestion was essentially what I had added to the SSL.pm module to get around the problem. I guess that my wording of the problem made it appear that I was asking the significance of the uninitiated variable, but I was really trying to understand why the SSL.pm was coded to require a proxy when in most cases a proxy is not used. Again, thanks for your great reply.

You can search the code for where $proxy_server is declared (by a my(), local(), or our() statement), and right after it initialize it to an empty value: $proxy_server = ''; That will remove the warning message.

If you find one, you should change the troublesome line of code to: $proxy_server =~ s|^https?://||i if defined $proxy_server; and *not* initialize the variable as specified above.
