Class Method Details
.get_http_object(uri) ⇒ Net::HTTP::Proxy
Return a Net::HTTP::Proxy object.
This method optionally configures SSL correctly if the URI scheme is ‘https’, including setting up the root certificate store so remote server SSL certificates can be validated.

.no_proxy?(dest) ⇒ Boolean
The documentation around the format of the no_proxy variable seems inconsistent. Some suggests the use of the * as a way of matching any hosts under a domain, e.g.:
*.example.com
Other documentation suggests that just a leading ‘.’ indicates a domain level exclusion, e.g.:
.example.com
We’ll accommodate both here.
