Created January 8, 2015 02:59
Patch node's TLS module to skip certificate name check
// This is a modified version of node's built-in tls.js patched not to check
// the server hostname against its certificate.
//
// node 0.10 does not support this in a clean way.
// This will be allowed in node 0.12 setting a checkServerIdentity function
// in the HTTPS agent config.
