I get the following exception when trying to request https pages.
I've read online about this a little and there are various suggestions
about how to solve this, however I'm not sure which approach is best.
My use case is to download pages and "scrape" contact information off
the page. Therefore, I'm not really concerned about the validity of
certs, etc, I just want to get the content.
Thanks,
