Thanks for the suggestions so far.

First, the easy suggestion to respond to - adding the proxy environment variable didn't seem to make a difference. Since it appears to have done no harm, I'll leave it in for now.

Second, shotgunefx - I read through the README.SSL file that came with libwww-perl-5.53. It sounds like LWP should work with https once you install Crypt::SSLeay, which requires OpenSSL. I've had no problems accessing https URLs, I've just had problems passing certificates to these URLs.

I've re-installed OpenSSL, and Crypt::SSLeay. I did discover that I had been pointing to an older version of OpenSSL, but even after I changed the OpenSSL path, my script still doesn't seem to be working.

Am I missing something in the README.SSL file? Any other ideas?

Thanks,
P.J.
