Work in progress. Seems like older Rubies do not like Resolv. I think I'll just grab the regex and put it in our net/http.rb.

Thank you, it looks great 👍 I just have a nitpick on test.

[st0012]

Could you add it to the net/http patch instead as it's required by it, not HTTPTransport.

/facepalm my bad, one sec

[natikgadzhi]

Done.

@st0012, cleaned things up!

• Resolved the conflict
• Explicit require "resolv"
• Better scoped unit test (thank you!)

Let's see how CI gods feel about it.
